Patient: Male, 84Final Diagnosis: Breast hemangiomaSymptoms: Feeling breast massMedication: —Clinical Procedure: —Specialty: SurgeryObjective:Rare diseaseBackground:Male breast hemangioma is a rare benign neoplasm that is usually excised for definitive diagnosis.Case Report:In our case report, we present a male octogenarian with multiple comorbidities who presented with a large palpable mass in his right breast. The diagnostic imaging studies were suggestive of a benign tumor, with a BI-RADS (Breast Imaging Reporting and Data System) score of 3. Subsequent core needle biopsies were diagnostic of benign hemangioma. The patient was managed with observation due to his comorbidities. Benign vascular tumors in the male breast are exceptionally rare, and in our review of the literature we found only 14 previously published cases. Historically, fine needle aspiration has been found to be unreliable in making a definitive diagnosis and surgical excision has been the standard treatment.Conclusions:Recent studies and our case report indicate that core needle biopsy may be a reliable diagnostic tool and observation is a possible option for hemangiomas in male patients who cannot undergo surgery.

Adenocarcinoma is the most common malignant neoplasm involving breast tissue. In contrast to carcinomas, the other types of malignant neoplasms involving the breast are relatively uncommon. One of the examples of this rare entity is lymphoma. Traditionally, non-Hodgkin lymphomas (NHL) involving the breast are divided into primary lymphoma of the breast and systemic lymphoma, although the distinction could be challenging. Most of NHL involving breast tissue have B cell origin; T cell NHL represents less than 20% of all lymphoma cases. Anaplastic large cell lymphomas (ALCL) involving the breast accounts for even lower percentage of cases. Similar to ALCL involving other sites, there are several main types of ALCL identified: primary cutaneous ALCL and systemic ALCL, which is subdivided into ALK positive and ALK negative subtypes. Relatively recently, an additional distinct subtype of ALK-negative ALCL was described, which is associated with textured breast implants and needs to be considered as a differential diagnosis if patient has a history of breast implants. Here, we report a case of ALCL presented as a breast mass without history of breast implant and discuss similar cases published in the literature.
