of Struma Ovarii: A Rare Ovarian Tumor

Abstract Struma ovarii or monodermal teratoma is a specialized ovarian neoplasm which mainly constitutes mature thyroid tissue. It is a rare tumor which comprises 1% of all ovarian tumors and 2.7% of all dermoid tumors. Thyroid tissue can be observed in 5-15% of dermoid tumors but to designate the tumor as struma ovarii, it must comprise more than 50% of the ovarian tissue. This study was conducted in the Department of Pathology, Manipal Teaching Hospital in Pokhara, Nepal over a period of 10 years (Jan 2006 to Sep 2015. Age, clinical findings, preoperative imaging diagnosis, size and side of the tumor, gross and microscopic findings along with type of surgery performed are included in the study. During this 10 years period, there were 7 cases of struma ovarii with age ranging from 26 to 56 years. 2 cases had tumor on the right and 4 cases had tumor on the left side while 1 case had bilateral struma ovarii. Initial presenting symptom was palpable mass, abdominal pain and vaginal bleeding. The size of the tumor ranged from 4 to 15 cm. The capsule was smooth and cut surface shows multiloculated cyst filled with greenish to pale brown gelatinous thick fluid. Microscopic examination revealed well encapsulated tumor composed entirely of thyroid follicles. Diagnoses of struma ovarii were made in all cases. The preoperative imaging may not exactly give the diagnosis. Clinically, lesser age group was more affected and left side is more commonly involved in our series, in contrary to other literature. Out of 7 cases, bilateral struma ovarii was seen in 1 patient. No malignant features were seen in any of these cases

Ganglioneuroblastoma in a newborn with multiple metastases: a case report

Abstract Background Ganglioneuroblastoma is a tumor of peripheral neuroblastic tissue which occurs predominantly in the pediatric age group; it is a rare occurrence in the newborn period with only one case reported at birth to date. Case presentation We report the case of a newborn male baby of Brahmin ethnicity from Nepal who presented with respiratory distress and blueberry muffin skin lesions after birth. A computed tomography scan showed a mass lesion in the posterior mediastinum, which was diagnosed as ganglioneuroblastoma on fine-needle aspiration cytology. He also had metastases to multiple sites including heart, lungs, skin and brain. Conclusions Ganglioneuroblastoma is a rare tumor in newborns. Any newborn presenting with respiratory distress associated with blueberry muffin skin lesions should be evaluated for neuroblastic tumor

A 14 Years Hospital Based Study on Clinical and Morphological Spectrum of Hydatid Disease

Introduction: Hydatid disease is endemic in sheep and cattle-raising areas worldwide. Its prevalence is high in Nepal. The study was carried out to determine the clinical, radiological and pathological presentations of hydatid disease. Methods: This was a retrospective study of all hydatid disease cases reported in Department of Pathology, from August 1996 to July 2010. All the clinical, radiological and pathological data were collected and collated. Results: A total of 51 cases of hydatidosis were studied. Patients presented with related symptoms in 47 cases, 92.16% with CI (84.78, 99.54) and asymptomatic in four cases, 7.84% with CI (0.46, 15.22). Involvement of liver and lung was found in 35 (68.63%) cases and 10 (19.61%) cases respectively. Involvement of other organs like kidney, pelvis and broad ligament were seen in 6 of the cases. Total 29 cases, 56.86% with CI (43.2, 70.46) had solitary cyst while rest of the cases had multiloculated cyst. All cases had radiological correlation and histopathological confirmation. Conclusions: Most cases presented with organ related vague symptoms, however it should be considered as a differential diagnosis especially in asymptomatic cases and cases with unusual sites. Imaging studies is useful in preoperative diagnosis and postoperative histopathology is confirmatory. A multicentric hospital based study will help to decrease the incidence. _______________________________________________________________________________________ Keywords: echinoccocus; hydatid cyst; hydatidosis

A Misdiagnosed Case of Hypertrophic Gastropathy

Hypertrophic gastropathy is a rare idiopathic hyperproliferative disorder which may present as Menetrier’s disease (MD) characterized by foveolar hyperplasia in the gastric fundus and body. It is often accompanied by a severe loss of plasma proteins (including albumin) from the altered gastric mucosa. The disease occurs in two forms, a childhood form due to cytomegalovirus infection and an adult form attributed to overexpression of transforming growth factor-alpha (TGF-α). The most common symptoms include epigastric pain with fullness and vomiting and generalized peripheral edema with hypoalbuminemia. We present a case of 75-year-old female presenting with epigastric pain and vomiting. Upper gastrointestinal endoscopy and computed tomography scan revealed an irregular mucosal fold at the body and antrum and thickening of the stomach wall, respectively. Though the endoscopic gastric mucosal biopsy was nonspecific, the patient underwent partial gastrectomy due to clinicoradiological suspicion of carcinoma. On histopathology, the case was reported as hypertrophic gastropathy, consistent with MD. Though there is a strong clinical and radiological suspicion of malignancy in the hypertrophied gastric mucosa, MD should be one of the important differential diagnoses

Clinico-pathological Study of Malignant Melanoma in A Tertiary Care Centre

Introduction: Malignant melanoma, which causes three fourth of all deaths related to skin cancer, is more common in Caucasian population compared to Asian population. There is no reliable information about malignant melanoma in Nepal hence an effort has been made to assess the clinical and pathological features of melanoma patients. Methods: This was a retrospective hospital based study done in the department of Pathology. All cases of malignant melanoma diagnosed on biopsy during a period of 13 years were retrieved, reviewed and collated. Results: We had 35 cases with age range from 15 to 84 years with the mean of 51.4 years and M: F of 1.3:1. The predominant site was lower extremities. Most cases were less than 3 cm. Majority of histologic subtypes were nodular melanoma 29 (82.8%) followed by mucosal lentiginous melanoma 3 (8.6%), superficial spreading melanoma 2 (5.7%) and acral lentiginous melanoma 1 (2.9%). Half (50%) of the excisional biopsies were at Clark’s level IV and 75% were at high Breslow thickness. Conclusions: The most frequent site in males and females were lower extremities and trunk respectively in contrast to Western studies where it is opposite. Nodular melanoma was the commonest histologic subtype while in other Asian studies and in Western studies majority were acral lentiginous melanoma and superficial spreading melanoma respectively.

Benign melanocytic lesions with emphasis on melanocytic nevi – A histomorphological analysis

Background: Melanocytic lesions are common and include both benign and malignant conditions. Benign melanocytic nevus may show varied microscopic features and should be differentiated from malignant lesions. In the present study, we analyse the histopathological pictures of different types of benign melanocytic nevi.Materials and methods: This study was a hospital based retrospective study and all the cases reported as melanocytic nevus in the period from Jan 2014 to June 2018 in the Department of Pathology, Manipal Teaching Hospital were retrieved and analysed in the study.Results: A total of 104 melanocytic lesions including 74 cases of benign melanocytic nevus were reported in the study period. Females were affected more with a female to male ratio of 1.8:1. The age range was 5 to 78 years with mean age of 28 years. Among the female patients, the commonest age group was 21-30 years while among the males; the most affected age group was 11-20. The commonest histopathological subtype was intradermal nevus comprising 73% cases followed by compound nevus.  On analysis of the different sites involved, face, head and neck were found to comprise 92% cases. Epidermal changes including hyperkeratosis, acanthosis were common in intradermal nevus. In most cases, tumor cells were arranged in nests. Melanin pigment was noted in majority of the cases. Secondary changes noted were chronic inflammation, fibrosis and multinucleated giant cells.Conclusion: Benign melanocytic nevus may present in varied age range and show wide spectrum of histological features. All pigmented lesions should be biopsied for its subtypes.</p

Hydatidosis of infratemporal fossa with proptosis – an unusual presentation: a case report and review of the literature

Abstract Background Hydatid disease is one of the common zoonotic diseases caused by the larval stage of Echinococcus granulosus. It is endemic in sheep-raising and cattle-raising areas worldwide and humans are an accidental intermediate host following the ingestion of the larvae. Head and neck involvement of echinococcosis is a rare entity and involvement of the infratemporal region is extremely rare even in endemic areas. Only a few cases of hydatid cysts located in the infratemporal fossa have been reported in the literature. Moreover, extension of the hydatid cyst into the intraorbital region and infiltrating into the surrounding orbital bone is even rarer. Case presentation We present a case of a 65-year-old Gurung Nepalese woman with painless proptosis of her left eyeball of 2 months’ duration with recent progressive diminution of vision for 15 days. Radiological findings showed a cystic mass in the left infratemporal fossa extending into the left orbit and involving the surrounding orbital bone. Surgical removal was carried out. On histopathological evaluation, it was reported as hydatid cyst infiltrating into the bone. She was prescribed albendazole and discharged after surgery. However, she was lost to follow up and returned after 15 months with recurrence and proptosis of the same eye. Repeat excision of the lesion was carried out and postoperatively she was administered tablet albendazole. She was found to be disease free after 6 months of follow up. Conclusions Clinical and radiological findings are important but may not be sufficient in the preoperative diagnosis of hydatid disease especially if rare sites are involved. Proptosis may be seen in several conditions and orbital or infratemporal hydatidosis, although rare, should be considered a differential diagnosis

Basal Cell Carcinoma in Cases with or without Xeroderma Pigmentosum

Introduction: Basal cell carcinoma is the most common form of cancer in humans and comprises the vast majority of skin cancers. It predominantly affects fair-skinned individuals, and its incidence is rapidly increasing. The objective of the study is to identify the epidemiology, its topography and different histological subtypes of basal cell carcinoma in patients with or without Xeroderma Pigmentosum. Methods: A cross-sectional descriptive study was conducted at Manipal Teaching Hospital, Pokhara from Jan 2009 to Dec 2016. Ethical approval was taken from MEMG/IRC/GA. The study included patients with a confirmed diagnosis of basal cell carcinoma irrespective of their age and sex. Results: This study showed 77 individuals with 91 biopsies of BCC including 5 cases of Xeroderma Pigmentosum. The predominant histological subtype was nodular with 41 (53.94%) cases, followed by the 14 (18.42%) cases of pigmented and 10 (13.15%) cases baso-squamous subtype. The most frequent sites of involvement were the head and neck, with predominance in the nasal and orbital region. The mean age was 57.68 years but the basal cell carcinoma in cases of Xeroderma Pigmentosum was seen more in younger age groups. There were 43 (55.84 %) male patients and 34 (44.16 %) female patients with a male to female ratio of 1.26:1. Conclusions: Nodular and pigmented varieties were the most frequent subtypes with nose being the commonest site of involvement. Basal cell carcinomas in cases of Xeroderma Pigmentosum were noted in younger age group with multiple lesions. Keywords:   basal cell carcinoma; recurrence; topography; xeroderma pigmentosum

Bilateral Synchronous Testicular Seminoma in a Patient with Bilateral Cryptorchidism

Cryptorchidism is a known cause of testicular tumor. The incidence of testicular tumor is 11 times more in inguinal testes and 50 times more in intra-abdominal testes. The position of the undescended testis is related to the likelihood of carcinogenesis with the intra-abdominal location having the highest risk for malignancy. Bilateral testicular tumors are rare and 80% of bilateral tumors are metachronous. Synchronous bilateral testicular tumors are rare and bilateral synchronous testicular seminoma in a patient with bilateral cryptorchidism is very rare.  Keywords: bilateral; cryptorchidism; seminoma; synchronous; testes
