Adenoma of the nipple is a very uncommon benign neoplasm of lactiferous ducts. Its clinical presentation is variable and it can be easily misdiagnosed as a malignancy such as mammary Paget disease or breast intraductal carcinoma. Although dermoscopy and imaging tests such as ultrasonography or mammography can be of help, histological examination is mandatory to confirm the diagnosis. We describe the clinical, dermoscopic, and histopathological findings in a patient with nipple adenoma and discuss the clinical and histological differential diagnosis as well as the different treatment options.

    Palmoplantar epidermoid cysts can range in clinical presentation from an asymptomatic slowly enlarging mass to a painful nodule. We report two cases: an epidermoid cyst on the sole and another on the palm. This article reviews the possible etiology, diagnosis, and prognosis of palmoplantar epidermoid cysts.

      Muscular hernias are an uncommon condition that typically present as subcutaneous nodules on the legs that appear or enlarge while standing or exercising. They are usually asymptomatic, although they may sometimes be tender or painful and may cause cramps, especially in athletes. Physical examination and ultrasound imaging are the key for determining the diagnosis. We present a 67-year-old woman with tender subcutaneous nodules on both lower legs in which dynamic ultrasound examination confirmed the diagnosis of muscular hernias.

        Alopecia induced by biological therapy is a rare side effect of this type of drugs. A total of 23 patients of psoriasiform eruptions with severe scalp involvement that induced alopecia during anti-tumor necrosis factor (anti-TNF) treatment of non-dermatological conditions have been previously reported. We present a 50-year-old man affected by plaque psoriasis that developed psoriasiform patches with alopecia over his scalp 10 months after initiating treatment with adalimumab. Punch biopsy of the alopecic area on the scalp revealed psoriasiform epidermal changes and alopecia areata-like dermal changes. Along with these findings, there was a dermal inflammatory infiltrate made up of eosinophils and plasma cells. In conclusion, scalp psoriasiform lesions with alopecia in patients treated with anti-TNF agents have been rarely reported. We describe a patient with anti-TNF therapy-related alopecia affected by psoriasis. Our patient has a peculiar histology with features of psoriasis and alopecia areata in addition to eosinophils and plasma cells. This entity may respond to topical treatment. However in patients of severe scalp involvement anti-TNF suspension should be considered.
