Métastases cutanées vues au laboratoire d’anatomie pathologique à Lomé, Togo entre 2005 et 2014

Introduction: L'objectif de cette étude était de documenter le profil épidémiologique et histologique des métastases cutanées vues au laboratoire d'anatomie pathologique (LAP) de Lomé. Méthodes: Il s'agissait d'une étude descriptive et transversale portant sur des cas de métastases cutanées observées au LAP du CHU Sylvanus Olympio entre 2005 et 2014.Résultats: Au cours de cette période d'étude, nous avons recensé 32 cas de métastases cutanées représentant 3,2% (1005 cas) de l'ensemble des cas de métastases enregistrées au LAP. L'âge moyen des patients atteints de ces métastases cutanées était de 42,6 ans et le sex-ratio (F/H) de 2,2. Sur le plan macroscopique, ces métastases étaient nodulaires dans 15 cas, bourgeonnantes dans 12 cas, ulcéré dans 3 cas et ulcéro-bourgeonnant dans 2 cas. Les types histologiques étaient représentés par les adénocarcinomes (19 cas, 59,4%), les carcinomes épidermoïdes (8 cas, 25 %), la maladie de Paget (3 cas, 9,4%), le carcinome à petites cellules du type neuroendocrine (un cas, 3,1%) et le mélanome (un cas, 3,1%). Selon le degré de différenciation, les métastases cutanées étaient bien différenciées dans 14 cas (56%). Les principales localisations de ces métastases cutanées étaient le thorax (11 cas, 34,4%) suivi de l'abdomen (10 cas, 31,3%). Les cancers primitifs étaient surtout d'origine mammaire (14 cas, 43,7%).Conclusion: Cette étude montre que les métastases cutanées sont relativement rares et les tumeurs malignes d'origine mammaire sont les tumeurs primitives prédominantes. Avec un pourcentage élevé des formes peu différenciées et celles indifférenciées, l'amélioration du plateau technique du LAP (immunohistochimie) permettra d'accroitre ses capacités diagnostiques

Disseminated Histoplasmosis Due to Histoplasma capsulatum var. duboisii in a Non-HIV Patient in Togo: A Case Report

Background: Histoplasmosis is a fungal infection due to Histoplasma capsulatum. We report a case of disseminated African histoplasmosis in an HIV uninfected patient in Togo.Case Report: A 35-year-old woman was admitted in dermatology for disseminated nodular lesions and left shoulder pain for 4 months. On examination, there were firm or softened nodular lesions with torpid ulceration and translucent molluscoid-like papules disseminated on the face, trunk, and limbs. There was also a painful swelling of the left shoulder, with an impotent upper limb. Histology showed an acanthotic epidermis discretely keratotic. In the dermis, there were granulomas with giant cells, histiocytes and polymorphonuclear cells around largely altered yeasts. The presence of Histoplasma capsulatum var. duboisii was confirmed by direct microscopic examination. Chest X-ray showed a left minimal abundance pleurisy. Shoulder x-ray showed heterogeneous lysis of the left humeral head and a large osteopenia of bones associated with left scapulo-humeral dislocation. The medical treatment was based on itraconazole (400mg/day) for 4 months relieved by fluconazole (450 mg/day) with good evolution after 4 months.Conclusion: A disseminated form of African histoplasmosis can be observed in non-HIV infected patients. The prognosis depends on the precocity of the diagnosis and the treatment

Pathologies cutanées vues au laboratoire d’anatomie pathologique à Lomé, Togo

Introduction: Les affections cutanées restent encore un problème de santé publique dans la majorité des pays en développement. Notre étude s'est fixée comme objectif de déterminer les aspects épidémiologiques et histologiques des dermatoses au Togo. Méthodes: Il s'agissait d'une étude descriptive et transversale portant sur les cas de dermatoses diagnostiquées de 2002 à 2013 (10 ans) au laboratoire d'anatomie pathologique (LAP) du CHU- Sylvanus Olympio. Tous les cas d'examen portant sur un prélèvement de peau (biopsie, exérèse, pièces opératoires) ont été colligés de 2002 à 2013 à partir des données des registres dudit laboratoire. Résultats: Au cours de la période d'étude, 1119 (7,6 %) des 14720 prélèvements reçus au LAP étaient des prélèvements de peau, ce qui correspond à une fréquence annuelle de 111,9 prélèvements. L'âge moyen des patients dont les prélèvements de peau appartenaient était de 35,4 ans et le sex-ratio (H/F) de 1,39. Au plan histologique, les lésions cutanées étaient reparties en dermatoses non tumorales (390 cas, 34,8%), dermatoses tumorales et pseudo tumorales (607 cas, 54,2%) et des dermatoses de diagnostic incertain (122 cas, 10,9%). La lèpre (95 cas, 8,5%) et le carcinome épidermoïde (134 cas, 11,9%) étaient les types histologiques les plus fréquents. Conclusion: Les dermatoses tumorales et pseudo tumorales font plus l'objet de demande d'examen anatomopathologique au Togo, ce qui s'explique par la hantise de tumeurs malignes devant toute dermatose tumorale. L'amélioration du plateau technique du LAP (immunohistochimie, immunofluorescence directe) permettra d'accroitre ses capacités diagnostiques.Keywords: Pathologie cutanée, histopathologie, Tog

Basidiobolomycosis in Togo: clinico-pathological study of a series of 12 presumed cases

Abstract Objective The purpose of our study was to describe the histological diagnosed of the Basidiobolomycosis cases from 1990 to 2017 (28 years) in the only Pathology Anatomy Laboratory in Togo. Results A total of 12 cases of suspected Basidiobolomycosis have been identified. The sex ratio (M/F) was 2. The average age of the patients was 24.8 ± 1.6 years. Six patients (6/12) had a pathological history: HIV infection (n = 4 cases) and tuberculosis (n = 2 cases). The clinical manifestations were localized to pure skin (n = 9 cases), skin and mucous digestive (n = 2 cases) and disseminated (n = 1 cases). Direct mycological examination and culture in 4 patients was positive in 3 patients. The samples examined consisted of 11 cutaneous biopsies measuring 1–3 cm and a biopsy of the intestinal mucosa. Histology showed granulomatous inflammation of the dermohypodermal site with numerous giant cells associated with eosinophilic polynuclear cells, in which there are 5–7 mm non-septate, irregular mycelial filaments. Patients were treated with ketoconazole at a dose of 10 mg/kg daily. The progression of the patients’ condition was favorable after 4 weeks of treatment with a regression of the closets size. Patients were completely healed after 8 weeks of treatment, without recurrence after 6 months. No deaths have been recorded

Lèpre au Togo: étude rétrospective de 2630 cas sur 15 ans [Leprosy in Togo: retrospective study of 2630 cases over 15 years]

Objective: The aim of this study was to determine the evolutionary trends, the clinical forms of leprosy cases notified in Togo and to map them. Methods: This was a retrospective study from 1 January 2000 to 31 December 2014 on all leprosy cases notified by all districts to the national leprosy control program (PNLL). Results: A total of 2,630 new cases of leprosy were notified. The mean annual incidence was 175.33 cases with extremes of 73 to 266 cases. The median age of patients was 40 years, and the sex ratio was 1.13. Children aged 0 to 15 accounted for 5.5% of the cases. The plateau region in the center of the country had the highest annual incidence (around 800 cases). Clinically, multibacillary forms accounted for 74.2% of cases. All patients were treated with multidrug therapy (MDT). The WHO grade 2 disease was found in 15% of patients and 9.5% were lost to follow-up. Conclusion: Our results confirm the elimination of leprosy in Togo. There is a high incidence of leprosy in some areas of the country, which may raise fears of a resurgence of the disease RÉSUMÉ Objectif: Le but de cette étude était de déterminer les tendances et les formes cliniques de lèpre notifiées au Togo. Méthode: Il s’agissait d’une étude rétrospective du 1er janvier 2000 au 31 décembre 2014 portant sur les cas de lèpre notifiés par l’ensemble des districts sanitaires au programme national de lutte contre la lèpre (PNLL). Résultats: Au total, 2630 nouveaux cas de lèpre avaient été notifiés. L’incidence annuelle moyenne était de 175,33 cas avec des extrêmes de 73 à 266 cas. L’âge médian des patients était de 40 ans, et le sex-ratio de 1,13. Les enfants âgés de 0 à 15 ans représentaient 5,5% des cas. La région des plateaux dans le centre du pays cumulait l’incidence annuelle le plus élevé (environs 800 cas). Sur le plan clinique, les formes multibacillaires représentaient 74,2% des cas. Tous les patients étaient traités par polychimiothérapie. L’infirmité grade 2 de l’OMS était retrouvée chez 15% des patients et 9,5% étaient perdus de vue. Conclusion: Nos résultats confirment l’élimination de la lèpre au Togo. On note une incidence élevé de la lèpre dans certaines régions du pays pouvant faire craindre une recrudescence de la maladie

Basidiobolomycosis Simulating a Mycobacterium ulcerans Infection in a Togolese Rural Child

Background. Basidiobolomycosis is a deep mycosis which preferentially affects rural young people in tropical countries. We report an atypical case, with multiple ulcers, simulating a Buruli ulcer. Case Report. A 5-year-old boy, living in a rural area, was seen for ulcers on the buttocks and at the back and right flank that had been in progress for 4 months. On examination, we found an infiltrated plaque with sharp edges, little painful, located on the buttocks, back, and the right flank. On this plaque, there were multiple ulcers with polycyclic contours and fibrinous bottom. There were inguinal inflammatory lymph nodes. The patient had an altered general condition. Examination of other organs was normal. The diagnosis of Buruli ulcer was evoked first; the search for Mycobacterium ulcerans by polymerase chain reaction was negative. Histology test performed revealed hypodermic granulomatous inflammation with predominant macrophage and eosinophils. The mycological culture was not done. The child was treated successfully with ketoconazole (10 mg/kg/day) during eight weeks. Discussion. Our observation shows great clinical and epidemiological similarities between basidiobolomycosis and Buruli ulcer. It confirms the efficacy of ketoconazole in severe basidiobolomycosis infection with alteration of general condition. Histopathology is very important for differential diagnosis between these two diseases

Prevalence and Clinical Characteristics of Aquagenic Pruritus among Medical and Pharmacy Students in Lomé (Togo)

Objective. The aim of this study was to determine the prevalence and clinical characteristics of aquagenic pruritus (AP) in medical students in Lomé (Togo). Methods. This was a prospective and descriptive study conducted among medical students in Lomé from June 1st to August 30th, 2019. The data collection questionnaire was anonymous composed of sociodemographic variables, bathing habits, and history of allergy responding to the concept of aquagenic pruritus and its characteristics. Results. In our study, 129/591 medical students had AP, giving a prevalence of AP to 21.8%. The average age of students with AP was 23.9 years, and the M/F sex ratio was 1.5. AP was not present after each bath in 100% of the medical students who suffered from it and lasted an average of 9.09 minutes. It was characteristically pruritic (60.5%) or tingling (38.0%) and localized (45.0%) or generalized (55.0%) in respondents with history of AP. There was a significant association between the presence of AP and a personal history of allergic rhinitis (p<0.01) and the presence of AP and a family AP (p<0.01). Twenty-six (20.2%) respondents with AP feared taking a bath. Bathing with warm or lukewarm water (29.5%) or applying menthol ointment (27.1%) were the main precautions taken to reduce AP. Conclusion. Aquagenic pruritus is a common condition in medical students in Togo. It occurs mainly in males and can be familial

Prevalence and Factors Associated with Self-Medication in Dermatology in Togo

Objective. This study aimed to determine the prevalence of and factors associated with self-medication in dermatology in Lomé, Togo. Methods. We conducted an analytical cross-sectional study from February to April 2016 in 2 dermatology departments in Lomé. Univariate and multivariate logistic regression models were carried out to identify possible factors associated with self-medication. Results. A total of 711 patients were included in the study. The mean age (±SD) of the patients was 26.6±6.9 years and the sex ratio (male/female) was 0.6. The main dermatologic diseases recorded were immunoallergic dermatoses (39.7%) and infectious skin diseases (22.6%). Two-thirds (481/711; 66.7%) of the patients had practiced self-medication before consultation in dermatology units. In multivariate analysis, factors associated with self-medication were female sex (aOR = 1.44; 95% CI = [1.01, 2.05]), duration of dermatologic disease more than one year (aOR = 1.79; IC = [1.19, 2.68]), adnexal dermatoses (aOR = 2.31; 95% IC = [1.03–5.21]), keratinization disorders (aOR = 4.23; 95% CI = [1.36–13.13]), and fungal skin infections (aOR = 5.43; 95% CI = [2.20, 13.38]). Conclusion. Our study confirms that self-medication practice is very common among patients with dermatologic diseases in Lomé and has identified associated factors

Multiple Squamous Cell Carcinoma in a Patient Using Skin Bleaching Products in Togo

Background. The cosmetic use of skin bleaching products is common among women in sub-Saharan Africa despite numerous reported cutaneous and systemic complications. We report the first case of squamous cell carcinoma in a woman using skin bleaching products in Togo. Case Report. A 65-year-old woman with a 30-year history of skin bleaching products use consulted in dermatology for a tumor of the neck that had been evolving for 2 years. There was no personal or family history of cancer. The patient was obese (BMI = 38.3 kg/m2) and had high blood pressure. Clinical examination noted multiple ulcerative and cauliflower tumors of the neck. The presence of stretch marks, skin atrophy, and ochronosis was noted in the examination of the rest of skin. There were no lymph nodes. HIV serology was negative. Histology of a tumor biopsy concluded to an invasive skin squamous cell carcinoma. The cervical, thoracic, abdominal, and pelvic TDM revealed pulmonary metastases. The patient underwent complete surgical removal of the right latero-cervical tumor. The left latero-cervical tumors were not removed because they infiltrated the large vessels. Chemotherapy before surgery was prescribed but not honored for financial reasons. The patient died 2 months after her first consultation in respiratory distress. Conclusion. Squamous cell carcinoma is one of the complications of skin bleaching in sub-Saharan Africa. It is necessary to intensify awareness campaigns on the complications of this practice, in order to reduce their incidence, in our context where this practice is very frequent

A Histopathological Study of Skin Lesions in Individuals with Oculocutaneous Albinism in Togo in 2019

Objective. The aim of this study was to study the histopathological patterns of skin lesions in persons with albinism (PWA) in Togo in 2019. Method. During two mobile skin care clinics in 2019, biopsies/excisional biopsies were performed in PWA in case of clinical doubt or in front of lesions suspected to be cancerous for histological examination. Anatomopathological reports were thus analysed. Results. During the two mobile skin care clinics, 115 biopsies/excisional biopsies were carried out in 79 PWA, with a mean age of 24 ± 16.1 years. Histological examination led to a diagnosis in 110 cases (95.6%) and was inconclusive in 5 cases (4 cases of uncertain histological diagnosis and one case of nonspecific histological lesions). Fourteen different histological diagnoses were made, with a frequency ranging from 0.9% (one case) to 26.9% (31 cases). The four most frequent diagnoses in descending order were basal cell carcinomas (BCCs) (31 cases; 26.9%), invasive squamous cell carcinomas (SCCs) or Bowen’s disease (23 cases; 20%), keratosis (20 cases; 17.3%), and cysts (seven cases; 6.1%). The 54 skin carcinomas were diagnosed in 33 (41.8%) of the 79 patients who underwent skin biopsies/excisional biopsies. The BCC/SCC ratio was 1.3. No cases of cutaneous melanoma had been diagnosed. Conclusion. Skin cancers represent the main histological diagnosis in PWA (46.9%) in Togo in 2019. The pattern of cutaneous malignancies in PWA shows the same trend as that seen in Caucasians with a predominance of basal cell carcinomas
