Undifferentiated Uterine Sarcoma: An Uncommon Case Report

Basaloid squamous cell carcinoma of the uterine cervix coexisting with undifferentiated sarcoma

Basaloid squamous cell carcinoma is uncommon tumor and has received little recognition, there are only a few cases in the medical literature. Correct diagnosis is important due to the high malignancy of this cancer and poor prognosis. We present a rare and interesting case of a basaloid squamous cell carcinoma of the uterine cervix in a 71-year-old female with prolapse of the uterus with co-existing atypical undifferentiated sarcoma.

Metastatic low-grade endometrial stromal sarcoma with sex cord and smooth muscle differentiation: A case report

BACKGROUND

Metastatic low-grade endometrial stromal sarcoma (LG-ESS) with sex cord-like and smooth muscle-like differentiation is rare. This article reports such a case with multiple recurrences and with extensive pelvic and abdominal metastasis.

CASE SUMMARY

A 47-year-old female patient was diagnosed with multiple cystic masses in the pelvic cavity by magnetic resonance imaging examination. Based on the postoperative pathological and immunohistochemical analyses of the surgical specimen, she was diagnosed with a metastatic low-grade endometrial stromal sarcoma with sex cord and smooth muscle differentiation.

CONCLUSION

LG-ESS is a low-grade malignant tumor with a high recurrence rate and metastasis probability. It is easily misdiagnosed initially. It is essential to distinguish LG-ESS with sex cord-like differentiation from uterine tumour resembling ovarian sex cord tumour.

HETEROTOPIC CARTILAGE IN THE MYOMETRIUM

We describe a rare case of chondroid heterotopia in the myometrium with associated foci of adenomyosis, in a 45 years old female, presenting with abnormal uterine bleeding and abdominal pain. Designated as metaplastic and benign, it needs to be differentiated from other benign conditions as impacted fetus, teratoma, chondroma, and certain malignant conditions like malignant mixed mullerian tumor, adenosarcoma and leiomyosarcoma.
