Case of fibromatosis of male breast

Desmoid fibromatosis in a male breast with gynecomastia: A case report

We present a unique case of a male patient with a history of gynecomastia, who sought medical evaluation due to the discovery of a palpable left breast mass. Mammography revealed a spiculated mass in the upper quadrant of the left breast at 10-o'clock, and subsequent ultrasound and MRI confirmed its presence. Ultrasound-guided biopsy identified the mass as desmoid fibromatosis. This case highlights the diagnostic challenge posed by desmoid fibromatosis, especially in men, as it can mimic breast cancer both clinically and radiologically. Desmoid fibromatosis, although locally invasive, does not metastasize and necessitates extensive resection due to a high recurrence rate.

Fibromatosis of the breast mimicking cancer: A case report

Breast fibromatosis, also referred to as desmoid tumor or aggressive fibromatosis, is a very rare, locally aggressive disease that does not metastasize. Bilateral lesions are extremely rare and are found in only 4% of patients with breast fibromatosis. Tumor recurrence following surgery occurs in 18%-29% of patients, most often within the first 2 years after surgery. In this report, we discuss a case of breast fibromatosis, mimicking a breast carcinoma both clinically and radiologically, that presented clinically with dimpling of the skin of the left breast in a 31-year-old woman. The patient relapsed a few months after surgery, with a multicentric and bilateral disease.

Fibromatosis of the male breast with concurrent florid-type gynecomastia: Report of a case and review of literature

Fibromatosis is a soft tissue lesion with infiltrative capacity, and is formed of proliferation of fibroblastic and myofibroblastic cells with a significant risk for local recurrence, but no metastatic potential. Fibromatosis is uncommon in the mammary gland, and accounts for less than 0.2% of all primary breast lesions. To the best of our knowledge, it has not been described in the setting of male breast with concurrent florid-type gynecomastia. We report a rare case of a 45-year-old male presenting with a palpable breast mass that was suspicious of carcinoma clinically. Failure of exclusion of metaplastic carcinoma and other lesions in repeated core biopsies lead to excision, which documented the intra-mammary origin of the lesion and established the diagnosis of fibromatosis. The current case demonstrates that fibromatosis in the male breast may have features and a presentation that can be confused with breast cancer. When obvious breast changes and history do not correlate with routine diagnostic measures, the presence of an unusual breast or chest wall tumor, such as a fibromatosis, should be considered in the differential diagnosis.

Fibromatosis of the breast in a 52-year-old man (2010: 10b)

Fibromatosis is a proliferation of fibroblastic and miofibroblastic cells that primarily originate from the fascia or aponeuroses of the abdominal wall. This entity has no potential metastatic risk, but can reappear locally. In rare cases it may develop in the breast, and it is extremely uncommon in the male breast. Fibromatosis of the breast presents clinical, mammographic and ultrasound signs of malignancy, and it can only be confirmed through histological analysis. We present the case of a 52-year-old man with a palpable and painless nodule in the right breast of 2 months' evolution with radiological signs of malignancy. The histological analysis determined that this was due to fibromatosis.

[Breast fibromatosis: An uncommon benign breast disease]

Extra-abdominal fibromatosis is an uncommon benign breast lesion resembling an infiltrative carcinoma in its clinical and radiological presentation. Surgical excision with wide margins remains the treatment of choice to avoid recurrence of this locally aggressive tumor. We present a case in which surgical biopsy allowed the diagnosis of a breast fibromatosis and we discuss its clinical, diagnostic, pathological and therapeutic particularities.
