[Histological study of a case of chondrocostal aspergillosis].
Histological study of biopsy specimens successively taken from the 7th, 5th and 6th right chondrocostal regions in a 33 year-old man; the patient was under chemotherapy for a diffuse lymphoma and has been operated for an aspergilloma of the right lung superior lobe. Non-specific chronic osteomyelitis was observed as well as Aspergillus fumigatus perichondritis (acute and chronic) which had lead to cartilage fragmentation. Cartilage fragmentation could be attributed to an enzymatic chondrolysis induced by polymorphonuclears inflammation. Such matrix degradation seems to favour the penetration of aspergillus into the cartilage surface. This case report recalls that fungi (including Aspergillus despite it appears exceptional) must be considered as a possible cause of osteomyelitis, particularly in immunosuppressed patients.
