Publication Darier White disease(Society of Dermatologists, Venereologists and Leprologists of Nepal (SODVELON), 2010) Amatya, A; Karn, D; Aryal, E; Makaju, R; Shakya, A; Priyadarshinee, AAbstract Darier’s disease was described inependently by Darier and White in 1989 AD. Reported prevalence varies from 1/100,000 in Denmark to 1 in 30- 35,000 in northern England and Scotland.1 Darier’s disease has been reported from other parts of the world, however,there has been no reported cases in Nepal. It is an inherited autosomal dominat disease characterized by dark crusty lesions over the seborrheic areas of the skin. We are reporting a case of Darier’s disease in a Nepalese patient who developed skin leison’s over his face and body at the age of 12 years. We took skin punch biopsy from the leisons, which showed findings suggestive of Darier’s disease. Our case was treated with isotrerenoin and topical keratolytics. He responded with the given treatment within two weeks of therapy.Publication Pagetoid Squamous Cell Carcinoma In-Situ of Esophagus(Kathmandu University, 2023) Priyadarshinee, A; Bhattacharya, BABSTRACT Squamous cell carcinoma (SCC) is the most common malignant tumor of the esophagus, however, pagetoid SCCIS is an extremely rare condition in esophagus.1 Pagetoid Squamous Cell Carcinoma In-Situ (SCCIS) has been described in skin and external genitalia frequently.2 Herein we report a case of pagetoid squamous cell carcinoma in-situ in a 50-year-old male with clinical information, histopathological and immunohistochemical findings. The patient was a 50 years male with dyspepsia,refractory to proton pump inhibitors (PPIs). In upper gastroduodenal endoscopy, there was no obvious lesion in the esophagus and only mild erythema was noted. Biopsy showed a surprising finding of full thickness high grade squamous dysplasia in the lining squamous epithelium with scattered single large atypical cells. These cells were present away from the foci of dysplasia. The cells were large and showed marked pleomorphism, vesicular nuclei, prominent nucleoli and abundant pale to eosinophilic cytoplasm. Immunohistochemistry (IHC) was positive for p63 and p53, which confirmed the diagnosis of pagetoid SCCIS. Pagetoid squamous cell carcinoma in-situ is one of the rare entities with subtle clinical presentation and endoscopic findings. Evaluation of this case signifies the importance of taking biopsies in the lesions which shows minimal mucosal change in the endoscopy.
