| 説明 | Although these structures may occasionally occur as inclusions within giant cells they are usually not encountered as inclusions but are found extracellulary in the sinusoids of granuloma-containing lymph nodes in sarcoidosis as well as in non-granulomatous lymph nodes from individuals with sarcoidosis and other conditions.H-W bodies are oval or spindle-shaped, range up to several microns in size, and appear yellow-brown with H&E stain . The pigment appears to be lipofuscin. Ultrastructural studies have shown that H-W bodies are giant lysosomes and residual bodies. They are acid-fast and stain with silver stains as well as a variety of other stains.When visualized with silver stains H-W bodies can be easily mistaken for budding yeasts due to clustering of individual bodies.H&E stain - oil immersion. |
