[Hidradenoma of the vulva (author's transl)]

Five cases of hidradenoma of the vulva are reported. The differential diagnosis is discussed. Painstaking microscopic diagnosis is very important since the hidradenoma may be confused with an adenocarcinoma. Local excision of the small tumour is the only treatment necessary.

Diagnosis of a papillary hidradenoma of the vulva by simultaneous cytology and colposcopy

A case of papillary hidradenoma of the vulva is reported, and the simultaneous use of cytology and colposcopy as diagnostic aids is suggested. The cytologic and colposcopic findings are described in detail. The cytologic findings correspond with the histologic pattern of these benign growths.

Hidradenomata of the external auditory meatus. (Review of the literature and report of a pleomorphic adenoma)

A case of hidradenoma of the external auditory meatus ('ceruminoma') is presented, with a review of the literature. The tumour has the appearances of a pleomorphic adenoma and is devoid of a capsule. It is suggested that the term hidradenoma be used for tumours of the ceruminous glands and that they be classified histologically as (1) adenoma, (2) pleomorphic adenoma, (3) adenoid cystic carcinoma and (4) adenocarcinoma. This classification aids treatment and prognosis. Attention is drawn to the high incidence of malignancy in hidradenomata of the external auditory meatus. The treatment of choice for pleomorphic adenomata is wide surgical excision with an adequate margin of normal skin. If there is doubt regarding complete removal, or a recurrence develops, a wider surgical excision is necessitated.
