We report such a case in a 19 years old female. Case presentation Case notes and histopathology were reviewed. Adenosquamous carcinoma was diagnosed on wide local excision and patient underwent skin-sparing mastectomy with Latissimus dorsi flap reconstruction. Conclusions Adenosquamous carcinoma of the breast is a rare form of metaplastic breast carcinoma. Data on correct management follow-up and prognosis are very limited but given the high potential for local recurrence aggressive surgery may be the only option. Background Adenosquamous carcinoma of the breast is a rare morphological variant of metaplastic breast carcinomas which was first described in early 1980s 1 2 . Since then several cases and case series have been reported. We present a case of adenosquamous carcinoma in a very young woman aged 19 years. We also present a minireview of literature on this known but rare histological type of breast cancer. Case presentation The 19 years old woman presented with approximately four weeks history of painless 5 X 5 cm breast lump lumpiness. There was no history of trauma nipple discharge or relation with menstrual cycle. There was no known family history of breast cancer. Palpation revealed a non-tender mobile hard left upper quadrant left breast lump. Mammogram was not performed given the very young age of the patient. Ultrasound revealed a prominent diffuse hypoechoic lesion. It appeared to be most likely benign lesion but as there was an element of uncertainty as to the nature of the lump on ultrasound an ultrasound guided core biopsy 14G needle was performed.
