We report a case of tubular apocrine adenoma located on the scalp, with characteristics of syringocystadenoma papilliferum in the superior part of the lesion. An interesting feature of the growth is its connective tissue involvement.

A 74-year-old man presented with a tumor on his scalp that he had since birth. The authors observed a verrucous pink crusted plaque. The tumor was clinically diagnosed as nevus sebaceus and was removed. Histopathologic study showed, arising from nevus sebaceus, a lobular neoplasm with the classic features of trichilemmoma. Desmoplasia was present in the center of the trichilemmomatous area. This description is typical of a special, uncommon type of trichilemmoma that histologically mimics invasive carcinoma.

Cutaneous angiosarcoma (AS) of the face and scalp of the elderly is a rare malignant tumour with a very poor prognosis. The variable presentation and the benign appearance of the cutaneous AS may often delay the correct diagnosis. Because it is extremely aggressive, only early detection and treatment can modify the prognosis. We describe a case of an old man who was diagnosed of AS of the face and scalp 1 month after developing the cutaneous lesion. After treatment with placitaxel, the lesion completely diminished. Unfortunately, he developed pulmonary fibrosis and died 6 months after diagnosis. Predisposing factors of this entity are also discussed.

We report 3 cases of congenital multiple glomus tumors seen during the last 5 years. One of them showed autosomal dominant inheritance with male-to-male transmission. The remaining patients had no family history of similar lesions. The clinical and histopathological aspects of our patients support the recently described type 2 segmental manifestation of multiple glomus tumors. One of the cases showed associated multiple and giant trichilemmal cysts with a linear distribution in the scalp.
