Isolated cysticercosis of breast mimicking a mass lesion: A case report.

INTRODUCTION AND IMPORTANCE: Cysticercosis is a zoonotic disease caused by the larval form of Taenia solium. Its occurrence as a breast lump is rarely observed and therefore presents significant diagnostic challenges, especially in non-endemic regions.

CASE PRESENTATION: A 25-year-old female patient presented with a lump in her left breast. The lesion was initially non-diagnostic on ultrasound and fine needle aspiration cytology. Excision biopsy of the cystic lesion was done, and histopathological examination confirmed it to be cysticercosis. Post surgery patient was given Albendazole, and she was asymptomatic during the 3 month follow up.

CLINICAL DISCUSSION: This case highlights the disease's ability to present in atypical forms, such as a breast lump, and the importance of considering cysticercosis in differential diagnosis, especially in endemic regions. Ultrasonography remains the preferred initial diagnostic modality, and the role of FNAC and histopathology is crucial for confirmation. The case also emphasizes the need for heightened clinical suspicion, even when traditional risk factors like pork consumption are absent.

CONCLUSION: This case emphasizes the importance of considering cysticercosis as a differential diagnosis for breast lumps, even with atypical presentation or in a non-endemic region. It highlights the need for greater awareness of this disease, stringent public health measures, and improved personal hygiene to combat its spread.
