Hypercalcemia and Unilateral Ovarian Mass in a Young Adult: A Case Report of Small Cell Ovarian Carcinoma

Patient: Female, 31-year-old Final Diagnosis: Small cell ovarian cancer • hypercalcemic type Symptoms: Abdominal pain • bloating Medication: — Clinical Procedure: Surgery • adjuvant chemotherapy • adjuvant radiotherapy Specialty: Oncology Objective: Rare disease Background: Small cell ovarian carcinoma, hypercalcemic type is an uncommon malignant ovarian tumor entity with an unfavorable prognosis and a short overall survival rate. It mainly affects women of childbearing age. Case Report: We report a case in which a 31-year-old woman with small cell ovarian carcinoma, hypercalcemic type presented with unspecific symptoms. We emphasize the importance of treatment planning and address fertility-sparing surgical procedures, which remain a therapeutic dilemma. Conclusions: The occurrence of unspecific abdominal symptoms, unilateral tumor masses, and hypercalcemia may indicate the presence of malignant ovarian neoplasm in young adults. Histopathological examination of the mass should be performed by an experienced gynecological pathologist. A misdiagnosis can lead to inadequate surgical and adjuvant treatment. Adjuvant multi-agent chemotherapy and high-dose chemotherapy with autologous stem cell rescue may prolong the progression-free interval and overall survival.
