Tinea nigra mimicking acral melanocytic nevi

Tinea nigra is a superficial infection caused by dematiaceous fungi. The clinical skin lesion is characterized by well-circumscribed brown–black macule patches on the palms and soles. In Asia, such pigmentation on these areas can be suggestive of acral lentiginous melanoma, which cause morbidity and mortality. Here, we report a case of a young patient with solitary black macule on the left palm for a year. Potassium hydroxide test was positive for pigmented short hyphae. The lesion subsided following topical antifungal treatment without recurrence. This report aims to provide insights into diagnosis of patients with pigmentations on acral areas.

Bullous and pustular cutaneous larva migrans: two case reports and a literature review

Abstracts: Cutaneous larva migrans (CLM) is a common skin infestation in tropical countries. The classic presentation is a serpiginous, migratory track on the feet. Local and systemic reactions, as well as secondary bacterial infections, are rarely reported. The authors report two cases of CLM with a blister and pustular response on uncommon body locations. The patients were treated with anthelmintic therapy, and a topical corticosteroid was used to relieve their severe reactions. This report aims to describe an infrequent presentation of a common disease and review treatment plans. Keywords: Blister, Bullous, Cutaneous, Hookworm infections, Larva migrans, Pustula

Verruca plana mimicking seborrheic keratosis in the elderly: A case report

Verruca plana is a common viral infection in childhood and early adulthood caused by the human papillomavirus. The clinical presentation can mimic that of benign epithelial neoplasms, particularly seborrheic keratosis, which is common in the elderly. We report a case involving an Asian female patient in her eighties who presented with multiple skin papules resembling seborrheic keratosis on her forehead. Based on the dermatopathologic studies, verruca plana was diagnosed. Keywords: Verruca plana, Flat warts, Seborrheic keratosis, Elderly, Geriatri

Recurrent extragenital herpes simplex type 2 occurring in a distal location of the same dermatome

Herpes simplex infection (HSV) is a common infectious disease, which the main clinical manifestations are mucocutaneous infection. Extragenital infections are reported in both type 1 and type 2 of herpes simplex virus. We report a case of a 33-year-old female with recurrent extragenital HSV type 2 infection on the right medial wrist. The patient had history of the previous infection site locating on the right posterior deltoid however both of two sites are the same dermatomal distribution. This report demonstrates the recurrent herpes simplex infection can develop in another area of the dermatomal distribution

Burkitt lymphoma initially mimicking varicella zoster infection

Burkitt lymphoma is an aggressive type of nodal non-Hodgkin lymphoma. This disease commonly involves the gastrointestinal tract, bone marrow, central nervous system, and in rare instances, the skin. We report the case of a 78-year-old Asian man who had experienced subacute fever and significant weight loss. He initially presented with a zosteriform skin rash on his right temporal area, which primary physicians diagnosed as varicella zoster infection and treated with antiviral drugs. The rash developed on the left forehead and chest. Dermatopathological studies on a skin lesion on the chest wall showed characteristics of Burkitt lymphoma. After a week of palliative chemotherapy, regression of all skin lesions was observed. This report aims to demonstrate an unusual zosteriform pattern of cutaneous involvement in Burkitt lymphoma

Zoster-like cutaneous metastatic adenocarcinoma of the lung: A case report

The zosteriform pattern is an infrequent cutaneous finding in oncologic patients who have a skin metastasis from a different primary source. Herein we report a case of adenocarcinoma of the lung which presented with zoster-like lesions along the thoracic dermatome. The histopathology indicated a metastatic neoplasm with variable glandular formations. Immunohistochemistry results pointed to the diagnosis of metastasized lung cancer. We suggest physicians should consider this rare diagnosis when experiencing similar cases

Clinicopathologic characteristics and survival outcomes of primary mucosal melanomas: A 10-year retrospective analysis from a single tertiary medical center in Thailand

Primary mucosal melanoma is a rare, aggressive neoplasm and there is limited data in Asian. We aim is to describe the clinicopathologic features and to evaluate overall survival rate (OS). We reviewed 17 cases over a 10-year period. The mean age was 60.9 ± 14.8 with 94.1% being female. The female genital tract was the principal location (52.9%). The most presenting symptoms were masses (88.2%), with 44.1% being amelanotic melanoma. The majority of patients (41.2%) had TNM stage IV. The median OS was 19.5 months, whilst the 1- and 3-year OS were; 70.6% (95% CI, 51.9–95.9%) and 9.8% (95% CI, 1.6–59.5%), respectively.
