Mammary Analogue Secretory Carcinoma
(MASC) is a recently described tumour
of the salivary gland, characterized by the
t (12; 15) (p13; q25) translocation. We
report a case from a 40 year old female
who presented with a tumour in the right
parotid gland at Social Service League,
MP Shah Hospital in Kenya. Histological
evaluation, immunohistochemical staining
and fluorescent in situ hybridization
(FISH) were done. The findings were
consistent with mammary analogue
secretory carcinoma of the salivary gland.
It is important to distinguish this
tumour from its morphological mimics.
At the time of writing of this paper, we
believed that this is the first case of
mammary analogue secretory carcinoma
described in Kenya.
