A 4-year-old Santa Gertrudis cow had epistaxis and loud nasal sounds associated with nasal granulomas. Multiple cutaneous granulomatous nodules were on the ears and single ones on the tail, vulva and thigh. Helminthosporium sp. was isolated from cultured lesions; two isolates from the ear and nasal mucosa were identified as H. speciferum. Tissue sections stained with hematoxylin and eosin contained rounded forms ranging from 5X5 micronM to 12X19 micronM; an indistinct hyaline wall surrounded granules and vacuoles of varying size. Occasional transverse septa were present. Periodic acid-Schiff, Gomori's

Silver and Gridley's Fungus stain treated sections contained numerous smaller pleomorphic buds and a few branching septate hyphae attached to the rounded forms.

Scleroma was diagnosed in nine of 30 Spanish-surnamed patients who had inflammatory lesions of the nose, pharynx, and larynx during the two-year period from Jan 1, 1978, through Dec 31, 1979. A total of 19 biopsy specimens were taken from these nine patients. In six of the 19 specimens, a histologic diagnosis of scleroma was not possible. Seventeen of the specimens with characteristic histologic findings stained with the peroxidase-antiperoxidase method for detection of Klebsiella capsular antigen III, although in 11 of these specimens, simultaneous cultures failed to reveal the characteristic Klebsiella rhinoscleromatis. These specimens showed the features of one of the three histopathologic forms of scleroma: ozena, granuloma, or scleroma. A range of tissue reactions was identified: histiocyte and plasma cell nodules, vasculitis, acute inflammation, pseudoepitheliomatous hyperplasia, ulceration, and submucosal keratin cyst. Comparison with histochemical bacterial stains revealed that the PAS and Hotchkiss-McManus stains gave unequivocal positive results less frequently than the immunoperoxidase method, and were less specific.

and Hopps were unreliable for the detection of the organism. The immunoperoxidase method can be appropriately used when the spectrum of histopathologic findings suggests a differential diagnosis of scleroma.
