S. Gori et al., PULMONARY SPOROTRICHOSIS WITH HYPHAE IN A HUMAN IMMUNODEFICIENCY VIRUS-INFECTED PATIENT - A CASE-REPORT, Acta cytologica, 41(2), 1997, pp. 519-521
BACKGROUND: Pulmonary sporotrichosis is a rare event. Sporothrix schen
ckii is a dimorphic fungus and develops at 37 degrees C in yeast form.
Usually hyphae are not observed in tissues, although their presence h
as been occasionally demonstrated in biopsies. CASE: A 37-year-old man
, human immunodeficiency virus-1 positive, with a CD4 cell count of 34
5/mm(3), developed a productive cough. A sputum smear revealed the pre
sence of a large amount of long, thin, septated micelia. The hyphae bo
re oval, sessile conidia. Cultures of sputum yielded numerous colonies
of S schenckii. CONCLUSION: This is the first report of hyphae of S s
chenckii in sputum. This case emphasizes the possibilities of cytology
for the diagnosis of mycotic infections. Fungi have typical morpholog
ies, and if is possible, on the basis of microscopic evidence, to susp
ect the nature of the infection early and thus to direct culture proce
dures.
