Diagnostic dilemma: axillary cysticercosis masquerading as breast mass

Cysticercosis, caused by the tapeworm Taenia solium, is a significant public health concern, particularly prevalent in developing nations. We present a case of isolated cysticercosis in the axillary region, mimicking a breast mass, in a 47-year-old woman who presented with a gradually enlarging mass in her right axilla and was initially diagnosed with fibroadenoma. However, further investigations revealed cysticercosis in the larvae, including ultrasonography and fine-needle aspiration cytology (FNAC). The patient underwent surgical excision of the cysts following a two-week course of albendazole therapy. Histopathological examination confirmed cysticercosis with a foreign body giant cell reaction. Cysticercosis typically involves muscular and subcutaneous tissues, posing diagnostic challenges due to its resemblance to other conditions. Ultrasonography, FNAC, and MRI play crucial roles in accurate diagnosis. Treatment involves a combination of surgical removal and antiparasitic medications such as albendazole. This case highlights the importance of considering cysticercosis in differential diagnosis, especially in endemic regions, and underscores the effectiveness of a comprehensive treatment approach integrating medical therapy and surgical intervention. Effective management ensures the eradication of parasitic infection and the alleviation of associated symptoms, exemplifying patient-cantered care for optimal outcomes. Increased awareness, preventive measures, and early diagnosis are essential for mitigating the burden of cysticercosis, particularly in regions with poor sanitation and high prevalence rates.
