Abstract
Treatment of primary cutaneous apocrine carcinoma of the scalp - case and review of the literature
Highlights
Primary cutaneous apocrine carcinoma (PCAC) is a rare type of sweat gland neoplasm with incidence rates estimated to range from 0.0049-0.0173 per 100,000 patients per year [1]
We report the case of a 42 year-old woman who presented with a 3 × 2 cm mass on the scalp treated with surgery and review reported cases in the literature on the prognosis, treatment and outcomes of PCAC
The initial pathology report showed a moderately-well differentiated adenocarcinoma. It was unclear at this time whether this was a primary lesion of the sweat gland or metastatic adenocarcinoma from another site
Summary
Primary cutaneous apocrine carcinoma (PCAC) is a rare type of sweat gland neoplasm with incidence rates estimated to range from 0.0049-0.0173 per 100,000 patients per year [1]. PCAC has a diverse presentation, occurring as both uniand multi-nodular growths with varying colour [2] Often these neoplasms are indurated, painless masses and can be associated with benign lesions [2], including a nevus sebaceous, most commonly seen with scalp lesions [4,5,6]. The initial pathology report showed a moderately-well differentiated adenocarcinoma It was unclear at this time whether this was a primary lesion of the sweat gland or metastatic adenocarcinoma from another site. Staging with CT scan of chest, abdomen and pelvis was negative for metastatic disease Her case and pathology was further reviewed at the multidisciplinary case rounds and it was concluded that with the histopathological features and absence of a breast primary carcinoma this was considered a primary apocrine carcinoma of the scalp. The patient is currently on surveillance and remains free of disease 39 months post surgery
