[ 1 ] - Diagnostic concordance among dermatopathologists in basal cell carcinoma subtyping: Results of a study in a skin referral hospital in Tehran, Iran
Background: Basal cell carcinomas (BCC) are the most prevalent among non-melanoma skin cancers (NMSC), which correspond to the most common skin cancers. BCC histopathological subtyping is a problem in therapeutic management. Therefore, we have decided to perform a histopathologic study for better classification of BCCs based on interobserver diagnostic judgment. Methods: We conducted this cross...

[ 3 ] - Porokeratotic eccrine ostial and dermal duct nevus (PEODDN): A case report
Porokeratotic Eccrine Ostial and Dermal Duct Nevus (PEODDN) is a rare disorder of keratinization that clinically resembles comedo nevus but occurs on the palms and soles and is characterized by cornoid lamella in the histopathology. We hereunder report a young male with mildly itchy papules on the lateral surface of the left foot who was diagnosed with PEODDN upon biopsy of the lesion. We brief...
[ 4 ] - Coexistence of Disseminated Superficial Actinic Porokeratosis and Ptychotropica Porokeratosis
Porokeratosis (PK) is an uncommon disorder of epidermal keratinization characterized by annular plaques with an atrophic center surrounded by a raised, keratotic wall, with unknown aetiology and an unpredictable outcome. It has several clinical forms including porokeratosis of Mibelli, giant porokeratosis, linear porokeratosis, disseminated superficial actinic porokeratosis, palmoplantar ...
[ 5 ] - Netherton syndrome: report of two cases
Netherton syndrome is a rare autosomal recessive condition with variable expression. It comprises an ichthyosiform dermatitis and erythroderma of variable intensity associated with hair abnormalities and features of atopy. The pathognomic (required for diagnosis) feature is trichorrhexis invaginata identified by microscopic examination of hair shaft. Ichthyosis linearis circumflexa is ano...
[ 6 ] - Diagnostic value of direct immunofluorescence of mucosal and skin biopsy specimens on formalin-fixed paraffin-embedded biopsy specimens compared to specimens placed in normal saline as the gold standard method in the diagnosis of a group of autoimmun
Background and Aim: Direct immunofluorescence (DIF) is represented as a gold standard method in diagnosis of autoimmune blistering dermatoses. Normal saline, liquid nitrogen and michel’ solution are a widely accepted media for preserving biopsy samples of skin or mucosa before DIF examination. Occasionally clinicians put the biopsy specimen taken for DIF in formalin 10%, occasionally clinicians...
