Summary
Two women experienced endometrial atypical complex hyperplasia with squamous hyperplasia. Histologic examination is crucial for diagnosis and ruling out adenocarcinoma.
Area of Science:
- Gynecologic Pathology
- Endometrial Cancer Research
Background:
- Endometrial atypical complex hyperplasia (ACH) is a precancerous condition.
- Squamous metaplasia can occur in the endometrium, but extensive forms are rare.
Observation:
- Two cases of endometrial ACH with extensive squamous hyperplasia were observed in women aged 48 and 31.
- Histological findings included increased gland-to-stroma ratio, squamous metaplasia, and glandular cytologic atypia.
- Necrosis was present in some metaplastic areas.
Findings:
- The study identified endometrial atypical complex hyperplasia co-occurring with extensive squamous hyperplasia.
- Histological features mimicked crowding due to squamous metaplasia, complicating diagnosis.
- Glandular cytologic atypia was a key finding.
Implications:
- Accurate histological examination is essential for diagnosing endometrial ACH and excluding adenocarcinoma.
- Recognizing extensive squamous hyperplasia is critical to avoid misdiagnosis.
- Further research may elucidate the relationship between squamous metaplasia and endometrial hyperplasia.

Cellular Adaptation IV: Dysplasia and Metaplasia
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
Cellular Adaptation III: Hyperplasia
Hyperplasia is an increase in the number of cells in a tissue or organ due to enhanced cell division. It is an adaptive, controlled response to stimuli such as injury, hormones, or stress, involving mitosis to produce genetically identical cells and support tissue repair and regeneration.Tissue CapacityCertain tissues, including the epidermis, intestinal epithelium, bone marrow, and fibroblasts, have a high potential for hyperplasia. Others, such as bone, cartilage, and smooth muscle, show...
