An apocrine hidradenoma is a benign adnexal neoplasm, usually covered by intact skin, but may show superficial ulceration and serous discharge. This feature is raising the possibility of malignancy as it was in our case of macroscopically suspicious tumour. We described cytomorphologic features of cutaneous nodule that might be a lead to the cytologic diagnosis of hidradenoma, but primary or se...

Warty dyskeratoma is a rare tumor that presents mainly as an isolated papule or nodule on the scalp, face or neck in the adults. Warty dyskeratoma frequently arises as a single lesion with a central keratotic plug on the skin of middle-aged or elderly people. Multiple warty dyskeratomas are very rare cutaneous lesions which are mostly seen on the scalp. We herein report a multiple warty dyskera...

Linear distribution of multiple subcutaneous nodules or ulcers along the course of lymphatics, classically seen in lymphocutaneous sporotrichosis, has been observed in a number of other infections like localized cutaneous leishmaniasis, cutaneous tuberculous and non tuberculous mycobacterial infections, Pasteurella tularensis, Scopulariopsis blochi, Nocardia brasiliensis, yaws and syphilis. A c...

IMPORTANCE Cutaneous metastases rarely develop in patients with cancer but have important implications for prognosis and treatment. While dermoscopy is useful for many skin lesions, few data exist regarding dermoscopic findings in cutaneous metastases. OBSERVATIONS We reviewed high-quality dermoscopic images of 20 outpatients with biopsy-proven cutaneous metastases and known diagnosis of unde...
