Summary
This study highlights a rare case of malignant epithelial mesothelioma diagnosed using electron microscopy. The tumor cells contained unique intracytoplasmic crystals, crucial for diagnosis.
Area of Science:
- Pathology
- Oncology
- Electron Microscopy
Background:
- Malignant epithelial mesothelioma is a rare cancer.
- Diagnosis can be challenging due to subtle histological features.
Observation:
- A 60-year-old female presented with respiratory symptoms and chest pain.
- Histology revealed tumor cells with eosinophilic cytoplasm, eccentric nuclei, and intracytoplasmic crystals.
- Electron microscopy identified large, intracytoplasmic crystalloid inclusions.
Findings:
- The tumor cells exhibited features consistent with malignant epithelial mesothelioma.
- Presence of intracytoplasmic crystalloid inclusions was a key diagnostic finding.
- Electron microscopy was essential for definitive diagnosis due to limited clinical information.
Implications:
- This case underscores the importance of electron microscopy in diagnosing rare tumors.
- Recognizing intracytoplasmic crystals can aid in identifying malignant epithelial mesothelioma.
- Further research into the origin and significance of these crystalline inclusions is warranted.

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
