Methods:
The findings suggested the differential diagnosis of Squamous cell
carcinoma, Basal cell carcinoma, and fibroma (fig .1). Laboratory test
results include hemoglobin (9.1 g/dl), Blood Sodium (129 mEq/L), and
Blood calcium (1.28 mg/dL).
Transvaginal ultrasonography (TVUS) demonstrated a normal uterus that
contains a paragard intrauterine device(IUD), normal left adnexa, and an
enlarged right ovary. On spiral computed tomography scan with
intravenous (IV) and oral contrast, the presence of a gallstone, an
oval-shaped cyst(4*7cm) on the right uterine adnexa, irregular, central
necrosis, oval mass(15*7*17cm) on the right labia majora, and a right
iliac lymphadenopathy is observed (fig .2).
An excisional biopsy was performed. The pathological examination result
confirmed the diagnosis of a benign fibroma with ulcerative epithelium
covering the surface of the mass, subepithelial inflammatory
infiltration which consists of lymphocytes, plasma cells, and
fibroblasts, with edema in the stroma, and no evidence of malignancy
(fig .3).
