Description of a Novel ERBB4 -rearranged Uterine Sarcoma.

High-grade endometrial stromal sarcoma (HGESS) is an uncommon tumor accounting for <1% of all uterine malignancies. Currently this designation is largely reserved for neoplasms harboring YWHAE-NUTM2A/B and ZC3H7B-BCOR translocations. Here, we report a novel CIQTNF1-ERBB4 translocation in a uterine neoplasm arising in a 49-yr-old woman with morphology suggestive of HGESS.

Vulvar basal cell carcinoma: clinical features and treatment outcomes from a tertiary care centre.

We retrospectively reviewed the clinical features, management and outcomes of patients diagnosed with basal cell carcinoma (BCC) of the vulva at the Gynaecological Cancer Centre, KK Women's and Children's Hospital, Singapore, between 1 January 2000 and 28 February 2014. Patients with vulvar BCC were identified from the cancer registry, and their medical records reviewed and analysed. A total of 11 patients with vulvar BCC were identified.

ZC3H7B-BCOR-Rearranged Endometrial Stromal Sarcomas: A Distinct Subset Merits its Own Classification?

A 41-yr-old lady with abnormal uterine bleeding underwent total abdominal hysterectomy. Histologic assessment revealed an endometrial stromal sarcoma (ESS) with minimal cytologic atypia and low mitotic count (up to 7/10 high-power fields) with only focal myxoid areas, morphologically corresponding to a low-grade ESS. Immunohistochemical stains showed cyclin D1 and CD10 positivity, and negative staining for CD117 and progesterone receptor.

Vaginal metastasis presenting as postmenopausal bleeding.

Vaginal cancer is rare worldwide and represents 2% of all gynaecological cancers in Singapore. Primary vaginal malignancies are rare and vaginal metastases constitute the majority of vaginal malignancies. Most of these metastases arise from the cervix, endometrium or ovary, although they can also metastasise from distant sites such as the colon, breast and pancreas.
