Mucocele Like Tumours (MLT) of the breast are quite rare neoplasms displaying a broad spectrum. These lesions were considered benign initially. But now, they are believed to be related to atypical ductal hyperplasia, ductal carcinoma, or mucinous carcinoma. Preoperative diagnosis in fine needle aspiration and core biopsy is difficult. We are reporting a case of mucocele like tumour with ductal carcinoma in situ and ductal carcinoma in a 71-year-old Turkish woman. The patient had a palpable mass in her left breast. Mammograpy showed ill defined and lobulated mass with widespread tiny microcalcifications. A few cells with sporadic nuclear atypia, were detected on FNAB (Fine Needle Aspiration Biopsy). Mastectomy was done on the left side because of the suspicion of malignancy as evident by mammograpy and FNAB. We examined adequate tissue samples from resection material. Histopathologic findings were consistent with MLT and microscopic focus of ductal carcinoma was also noted in mastectomy specimen. She is currently disease-free in the 118th month. We believe that our case will be the first patient from Turkey and will be added to the database as one of the longest term follow-up MLT cases reported. If a mucocele-like tumour is suspected in fine needle biopsy, surgical excision should be recommended and the specimen should be carefully evaluated to exclude the presence of ductal carcinoma in situ or carcinoma.
