Primary primitive neuroectodermal tumor of the uterus: a case report

Area of Science:

• Gynecologic Oncology
• Pathology
• Neuroendocrine Tumors

Background:

• Primitive neuroectodermal tumors (PNETs) originate from Kulchitsky cells and are commonly found in the gastrointestinal tract and lungs.
• PNETs are exceptionally rare in gynecologic practice, making their occurrence noteworthy.

Observation:

• A case of PNET arising in the uterine corpus of a 22-year-old woman is presented.
• The tumor exhibited a unique pseudocyst formation within the myometrium.
• Crucially, there was no evidence of endometrial invasion.

Findings:

• This represents the first documented instance of small-cell carcinoma of the uterine corpus with myometrial pseudocyst formation.
• The histological and clinical characteristics of this rare uterine PNET are detailed.

Implications:

• This case expands the known spectrum of PNET presentation in the female reproductive system.
• It highlights the importance of considering rare diagnoses in gynecologic pathology.
• Further research may elucidate the specific pathogenesis and optimal management of uterine PNETs.
