Primary Endometrial Squamous Cell Carcinoma In Situ: Report of a rare disease

Treatment of primary squamous cell carcinoma of the endometrium and review of previous literature: A case report

RATIONALE

Primary squamous cell carcinoma of the endometrium (PSCCE) has been occasionally reported. Treatment of this disease poses a challenge to clinicians because of its rarity. Herein, we report the case of a 56-year-old woman with typical clinical manifestations and a pathological diagnosis classified by molecular typing as having high microsatellite instability (MSI-H) PSCCE. Based on a review of the previous literature, we summarized the treatment options for this rare disease and proposed new opinions.

PATIENT CONCERNS

A 56-year-old woman was admitted to our hospital with irregular vaginal bleeding and lower abdominal swelling.

DIAGNOSIS

The patient was diagnosed with squamous cell carcinoma of the endometrium (stage IIIC1; MSI-H).

INTERVENTIONS

The patient underwent total abdominal hysterectomy, bilateral salpingo-ovariectomy (bso), and pelvic lymph node dissection. Following the surgery, the patient received adjuvant chemoradiotherapy.

OUTCOMES

The patient was followed up regularly. No recurrence or metastasis has been reported to date.

LESSONS

Curettage specimens may show only well-differentiated squamous epithelium, which is indistinguishable from normal squamous epithelium. It is difficult to infer from the histological morphology that the curettage specimens originate from the uterine cavity, which makes it difficult to diagnose PSCCE before the operation. We suggest that when an imaging examination indicates a tumor in the uterine cavity, even if multiple curettage specimens indicate normal or well-differentiated squamous epithelium, it indicates the possibility of PSCCE.

Primary squamous cell carcinoma of the endometrium in a woman of reproductive age: a rare case report

Primary endometrial squamous cell carcinoma is an extremely rare tumor that tends to occur in postmenopausal women. We report on a 33-year-old woman who presented with a history of irregular vaginal bleeding for more than 2 years, and a vaginal mass for more than 1 month. Biopsy of the vaginal mass revealed an invasive poorly differentiated squamous cell carcinoma. The patient underwent radical hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic lymph node dissection, peritoneal sampling and vaginal tumor resection. On the basis of her medical history, auxiliary examination and postoperative pathology, the patient was diagnosed with stage IV endometrial squamous cell carcinoma. The patient was followed-up regularly and remained in good condition.

Primary Endometrial Squamous Cell Carcinoma in-situ with Extensive Icthyosis Uteri: A Rare Case Report

Primary squamous cell carcinoma of the endometrium is a rare entity with primary endometrial squamous cell carcinoma in-situ being more uncommon. We report a 60-year-old multiparous post-menopausal woman who presented with a lower abdominal swelling alongwith difficulty in urination for five months. Total abdominal hysterectomy with bilateral salpingo-oophorectomy showed an enlarged uterus with pyometra. A diagnosis of primary squamous cell carcinoma in-situ of the endometrium was made on histopathology.
