Abstract

Introduction: Accessory breast tissue is a rare condition occurring in 1-3 % of males, primarily in the bilateral axillary region. Kajava Class I accessory breast, characterized by glandular tissue, an areola, and a nipple, is rarely reported. This case report highlights the clinical presentation, diagnostic approach, and management of this rare entity in an elderly male.

Case presentation: A 72-year-old male presented with a left axillary swelling since his early twenties. Initially painless and lemon-sized, the mass progressively enlarged, extending over the left chest and flank, causing dis- comfort and restricting daily activities. Physical examination revealed a large, pedunculated mass measuring 25x15x10 cm in the left axilla, with a smooth surface and no skin color changes except in the nipple and areolar region. Diagnostic imaging and cytology confirmed the presence of glandular tissue, and biopsy validated the diagnosis with histologic findings that showed lobules of glandular tissue lined by bland, single-layered ductal and myoepithelial cells, disposed in a fibrous growth background. Additionally, there were foci of bland fat tissue in the histology. Surgical removal of the mass resulted in a successful outcome.

Clinical discussion: The occurrence of Kajava Class I accessory breast tissue in an elderly male is rare. It is important to consider accessory breast tissue in the differential diagnosis of long-standing unilateral axillary swellings. The diagnostic approach included clinical examination, imaging, and histopathology. Surgical excision provided symptomatic relief and pre- vented potential complications such as malignancy.

Conclusion: Kajava Class I accessory breast tissue, though rare, should be considered in elderly males with long-standing unilateral axillary swelling. Early recognition and surgical intervention are crucial for optimal outcomes.

男性单侧巨大腋窝副乳房1例。
附件乳腺组织是一种罕见的疾病,发生在男性的1- 3%,主要发生在双侧腋窝区域。Kajava I类副乳房,以腺组织、乳晕和乳头为特征,很少报道。本病例报告强调临床表现,诊断方法,和管理这种罕见的实体在老年男性。病例介绍:一名72岁男性,二十出头就出现左腋窝肿胀。最初无痛,柠檬大小,肿块逐渐扩大,延伸到左胸和侧腹,引起不适并限制日常活动。体格检查发现左侧腋窝有一个25x15x10cm的带梗大肿块,表面光滑,除乳头和乳晕区外无皮肤颜色变化。诊断成像和细胞学证实了腺组织的存在,活检证实了组织学结果的诊断,腺组织的小叶被淡色的单层导管细胞和肌上皮细胞排列,在纤维生长背景下。组织学上可见淡性脂肪组织灶。手术切除肿块的结果是成功的。临床讨论:老年男性发生Kajava I类副乳腺组织是罕见的。在鉴别诊断长期单侧腋窝肿胀时,考虑副乳腺组织是很重要的。诊断方法包括临床检查、影像学和组织病理学。手术切除提供了症状缓解和预防潜在的并发症,如恶性肿瘤。结论:Kajava I类副乳腺组织虽然罕见,但在长期单侧腋窝肿胀的老年男性中应予以考虑。早期识别和手术干预对获得最佳结果至关重要。
