Insights
Cylindroma is a rare benign breast tumor. Fine-needle aspiration cytology revealed characteristic "jig-saw" patterns and extracellular material, aiding diagnosis.
Area of Science:
- Oncology
- Pathology
Background:
- Cylindroma is a benign adnexal tumor typically presenting as solitary dermal nodules on the scalp and forehead.
- Cylindroma of the breast is an exceptionally rare clinical finding.
Observation:
- This report details a case of a 61-year-old female patient with a breast lump.
- Fine-needle aspiration (FNA) was the initial diagnostic procedure performed.
Findings:
- Cytomorphological analysis of the FNA sample showed characteristic features of cylindroma.
- These included islands of tumor cells exhibiting a "jig-saw" pattern and bland, basaloid cells.
- Globular extracellular material was also observed, consistent with cylindroma.
Implications:
- Accurate cytological diagnosis of breast cylindroma is crucial.
- Distinguishing cylindroma from adenoid cystic carcinoma is essential due to differing management strategies.
Abstract:
Cylindroma is a benign adnexal tumor, which occurs as solitary dermal nodules on the scalp and forehead. Cylindroma of the breast is a rare lesion. Fine-needle aspiration is often the first line of investigation. In this communication, we illustrate the cytomorphological feature of cylindroma in a 61-year-old female patient who presented with a breast lump. Fine-needle aspiration cytology in this case reveals the islands of tumor cells formed a "jig-saw" pattern, along with the bland, basaloid cells associated with globular, extracellular material. These features are typical of cylindroma, but differential diagnosis of adenoidcystic carcinoma should always be kept in mind as the management of both tumors are different.
