Digital Papillary Adenocarcinoma: Case of a Rare Malignant Cutaneous Tumor of the Eccrine Sweat Gland.

Digital papillary adenocarcinoma (DPA) is a rare cutaneous tumor originating from the eccrine sweat glands. These lesions occur almost exclusively on the digits of the hands and feet, where there is a high concentration of eccrine glands. The diagnosis is made histologically, and the course of the malignancy tends to be very aggressive with high rates of recurrence and early metastasis at the time of diagnosis.

Trichophytic granuloma of the vulva.

Fungal infections causing deep tissue involvement are known as trichophytic granulomas. We describe an unusual case of trichophytic granuloma presenting in the vulva of a 39-year-old woman.

Melanoma arising in nevus spilus.

Nevus spilus is a pigmented skin lesion composed of a pigmented macule on which darker lesions appear at a later stage. There are an increasing number of reports of malignant melanoma occurring within these lesions, leading to greater concern regarding the malignant potential of these lesions. We describe the case of a fatal malignant melanoma arising in a congenital nevus spilus.
