Primary Extramammary Paget's Disease in a Male Patient Exhibiting Genital Involvement Mimicking Clinical and Histopathological Features of Bowen's Disease: A Case Report.

Extramammary Paget's disease (EMPD) is a rare cutaneous neoplasm characterized by the proliferation of malignant glandular-origin cells within the epidermis, occurring in areas other than the mammary areola. It is more prevalent in women (65%) than men (14%). Diagnosis can be confused with other neoplastic, inflammatory, or infectious conditions, often leading to initial inappropriate treatment with antifungals or topical steroids.

Idiopathic Atrophoderma of Pasini and Pierini: Response to Mycophenolic Acid Treatment.

Atrophoderma of Pasini and Pierini (APP) is a rare skin condition of unknown etiology. It is characterized by dermal atrophy with single or multiple hyperpigmented, non-indurated, and slightly depressed plaques on the trunk or limbs; unlike morphea, this condition does not cause induration. In this report, we analyze the case of a patient diagnosed with APP with a 19-year history of progression, aiming to highlight the few cases published in the literature.

[Metastatic breast melanoma in a man: Case report].

Background: Malignant melanoma is a skin neoplasm that typically does not invade the breast, making its spread to the breast tissue in a male patient uncommon. When it metastasizes to the breast, it can present as a palpable mass or even be asymptomatic. Ultrasound allows for the detection of round hypoechoic lesions, while mammography detects well-defined nodules with increased density.
