Fine-Needle Aspiration Cytology- Features of Carcinoid Tumours

 Dr Sampurna Roy MD    





Image:  FNAC- Carcinoid tumour - Groups of small regular cells with delicate cytoplasm, vesicular nuclei and prominent nucleoli. Rosette arrangement of cells present.

Samples may be profusely cellular in typical, atypical and metastatic carcinoid tumors.

Cell sheets and widespread cell dissociation both present.

Architectural features including palisades and rosettes are strong clues.

The cytoplasm is fragile and often shows faint eosinophilic granules with Papanicolaou staining.

Bare nuclei with granular chromatin are seen.

Spindle cell carcinoids show elliptical nuclei with granular chromatin and visible nucleoli.

Plexiform capillary fragments may be obtained, with tumour cells attached.

Scanty necrosis is seen in atypical and metastatic carcinoids.
