Abstract：
Perianal basal cell carcinoma (BCC) is a rare occurrence, with limited documented cases in the existing literature. The precise etiology contributing to its onset remains inadequately elucidated. Macroscopically, perianal BCC often exhibits atypical features, potentially leading to diagnostic challenges. Histopathological examination plays a crucial role in distinguishing BCC from other cutaneous lesions in this region. Despite its localized nature, perianal BCC generally carries a favorable prognosis characterized by a gradual progression. However, diligent follow-up is essential to mitigate the risk of recurrence. Our clinical observation highlights a noteworthy yet uncommon manifestation. The patient, a 64-year-old male, presented with a persistent perianal lesion evolving over a three-month period. Symptoms included intermittent bleeding and purulent discharge, exacerbating the clinical picture. A biopsy was subsequently performed, confirming the diagnosis of basal cell carcinoma. Following this, the patient underwent external beam radiation therapy as part of the treatment regimen.
摘要：
肛周基底细胞癌（BCC）是一种罕见的发生，现有文献中记录的案例有限。导致其发作的确切病因仍未充分阐明。宏观上,肛周BCC通常表现出非典型特征，可能导致诊断挑战。组织病理学检查在区分该区域的BCC与其他皮肤病变中起着至关重要的作用。尽管其局部性质，肛周BCC通常具有以逐渐进展为特征的良好预后。然而,努力的随访对于降低复发风险至关重要.我们的临床观察突出了一个值得注意但不常见的表现。病人,一个64岁的男性,表现为持续的肛周病变，持续三个月。症状包括间歇性出血和脓性分泌物，加剧了临床表现。随后进行了活检，确认基底细胞癌的诊断。在此之后,作为治疗方案的一部分,患者接受了外部束放射治疗.
