Poroma is a benign adnexal neoplasm with atn "poroid"/ductal differentiation that mimics benign and malignant skin tumors. Histopathology shows circumscribed proliferation of poroid cells intermingled with a variable number of cuticular cells. We report a case of pigmented poroma located on the face that simulated clinically and dermatoscopically a pigmented basal cell carcinoma. The features o...

Background & Objective: This study was designed for the first time for the detection of mutant BRAF V600E and its correlation with clinicophathologic features in a sample of Iranian patients with pathologically proved pigmented skin neoplasms.Methods: 82 paraffin-embedded blocks, including melanocytic nevi, malignant melanoma, Basel cell carcinoma, and sq...

Eccrine poroma is a benign adnexal neoplasm that clinically may mimic malignant skin tumors such as squamous cell carcinoma and amelanotic melanoma. The dermoscopic features of pigmented and nonpigmented eccrine poroma have recently been described. We present 2 cases of eccrine poroma, with their dermoscopic features. The lesions were characterized by multiple red lacunes and a polymorphous vas...

The incidence of skin cancer is increasing by epidemic proportions. Basal cell cancer remains the most common skin neoplasm, and simple excision is generally curative. Squamous cell cancers may be preceded by actinic keratoses-premalignant lesions that are treated with cryotherapy, excision, curettage or topical 5-fluorouracil. While squamous cell carcinoma is usually easily cured with local ex...

Bednar tumor is a rare skin neoplasm, considered to be a pigmented variant of dermatofibrosarcoma protuberans. Diagnosis is confirmed through histopathologic examination and immunohistochemical evaluation. Bednar tumor is aggressive locally and recurrences are frequent, but metastases are rare. The most appropriate therapeutic procedure is Mohs' micrographic surgery. The case report presents a ...

Background and aim: Basal Cell Carcinoma (BCC) is the most common skin neoplasm and the most common type of cancer. Since the incidence of injury is taken into consideration in the pathologic diagnosis, the study of clinical and microscopic views of BCC is of particular importance. The present study aimed at determining the frequency of clinical and microscopic views of BCC in a 10-year period ...

A 23-year-old man had a lesion in the right inferior iris which appeared to have enlarged since it was first seen when the patient was aged 5 years. The lesion was excised by a partial iridocyclectomy. Histopathologically the neoplasm was composed of both pigmented and non-pigmented cells. Pseudoacini, containing acid mucopolysaccharides, were present throughout the tumour matrix. Electron micr...
