Follicular dendritic cell sarcoma, abbreviated FDCS, is a very rare malignant tumour.
It is also known as follicular dendritic cell tumour (abbreviated FDCT),[1] and follicular dendritic cell neoplasm.[2]
General
- Very rare.
- Behave like a low-grade sarcoma.[3]
- Reported association with Castleman disease (hyaline-vascular type).[3]
WHO 2001 classification of dendritic cell neoplasms:[4]
- Langerhans cell histiocytosis.
- Langerhans cell sarcoma.
- Interdigitating dendritic cell sarcoma/tumour.
- Follicular dendritic cell sarcoma/tumour.
- Dendritic cell sarcoma, not specified otherwise.
Gross
Features:
- Often a head and neck lesion.[citation needed]
Microscopic
Features:[3]
- Oval or spindle-shaped cellular & nuclear morphology.
- Variable architecture (sheets, fascicles, whorles, storiform pattern).
- Nuclei:
- Small nucleoli.
- Clear or dispersed chromatin.
- Multinucleated cells.
- Interspersed small lymphocytes - distinctive feature.
- +/-Necrosis.
- +/-Marked nuclear atypia.
- +/-Abundant mitoses.
DDx:
- Histiocytic sarcoma.[5]
- Thymoma.
- Spindle cell lesions such as sarcomatoid carcinoma.
- Meningioma.[citation needed]
