A Unique Role of the Oncoplastic Breast Surgeon's Approach to an Inframammary Proliferating Trichilemmal Cyst: A Case...

Trichilemmal cysts, also known as pilar cysts, are commonly found on hair-bearing surfaces, such as the scalp or hairline. These are cysts that form from hair follicles and are benign. We describe an unusual case of a middle-aged lady presenting with a longstanding left-sided inframammary mass that had started growing more in the last year prior to the presentation. She was referred to the breast surgery clinic for further evaluation. A magnetic resonance imaging (MRI) scan was done for further delineation, which was not distinguished, and histopathological correlation was suggested. A decision was made for en bloc surgical resection with oncoplastic principles, ultimately resulting in a good cosmetic outcome for the patient.
