Coexistence of metaplastic carcinoma of the breast with tuberculous axillary lymphadenopathy: A rare occurrence

Metaplastic breast carcinoma (MBC) is a rare malignant neoplasm of the breast which is highly aggressive and is known for its early recurrence and poor prognosis. Concurrent detection of a MBC and tuberculosis of the axillary lymph node is a rarity. To the best of our knowledge, there is no such case report in the literature. A 35-year-old premenopausal woman was diagnosed as a case of left carcinoma breast with a left axillary lymph node. Core-needle biopsy of the breast was suggestive of squamous cell carcinoma. The patient underwent modified radical mastectomy with a latissimus dorsi myocutaneous flap. The postoperative biopsy of the breast and axilla revealed MBC and tuberculous lymphadenitis of the axillary lymph node. The patient received antitubercular therapy and radiotherapy, followed by chemotherapy and had no recurrence on follow-up. This case report emphasizes that metaplastic carcinoma breast can coexist with tuberculous axillary lymphadenopathy.
