Uterine cervical malignant granular cell tumor

Area of Science:

• Gynecologic Oncology
• Surgical Pathology
• Oncology

Background:

• Malignant granular cell tumors (MGCTs) are rare, accounting for 1-2% of all granular cell tumors.
• MGCTs are uncommon in atypical locations like the uterine cervix and exhibit rapid growth.
• These tumors can recur post-surgery, often with a poor prognosis.

Observation:

• A 37-year-old woman presented with irregular vaginal bleeding.
• Cervical biopsy revealed an incidentally diagnosed malignant granular cell tumor.
• The tumor involved approximately half the depth of the cervical stroma.

Findings:

• Neoadjuvant chemotherapy with isophosphamide, etoposide, and cisplatin was administered.
• Surgical excision of the cervical lesion was performed.
• No local recurrence or distant metastasis was detected on computed tomography during a 26-month follow-up.

Implications:

• This case demonstrates the potential efficacy of neoadjuvant chemotherapy followed by surgery for cervical MGCT.
• Early diagnosis and multimodal treatment may improve outcomes for this rare malignancy.
• Further research into optimal treatment strategies for cervical MGCT is warranted.
