Alopecia neoplastica in a patient with gastric carcinoma.

A well-recognized but rare presentation of scalp metastasis is alopecia neoplastica, which occurs as a single or multiple areas of cicatricial alopecia. Alopecia neoplastica is usually a presentation of metastasis from breast cancer, and other primary sites are extremely rare. We report a 36-year-old woman with alopecia neoplastica due to metastasis from gastric carcinoma. She also had pelvic metastases. An asymptomatic erythematous alopecic plaque had developed 10 months before presentation and biopsy was consistent with scalp metastasis. Total abdominal hysterectomy and salphingo-oophorectomy was performed and chemotherapy was proposed.
