Title: Complex adnexal tumours of the skin: a report of three cases and review of literature. Author: London V, Saadat P, Vadmal MS. Journal: J Clin Pathol; 2012 Sep; 65(9):819-22. PubMed ID: 22554961. Abstract: AIMS: Complex or composite adnexal tumours of the skin (CATS) are unusual neoplasms composed of two or more histopathologically distinct subtypes of appendageal neoplasms coexisting in a single cutaneous lesion. The authors report three examples of CATS, review literature and discuss their probable histogenesis. METHODS AND RESULTS: Of the three tumours described, one tumour showed a mixture of a proliferating pilar tumour and syringocystadenoma papilliferum, the second lesion was composed of a proliferating pilar tumour and tubulopapillary hidradenoma and the third tumour exhibited a syringocystadenoma papilliferum and tubulopapillary hidradenoma in combination. CONCLUSIONS: CATS are rare tumours. The authors reported three unique cases in addition to the 10 other reported cases. These three cases further strengthen the hypothesis of a 'folliculosebaceous apocrine' unit as the most likely point of origin of CATS.[Abstract] [Full Text] [Related] [New Search]
