[Traqueíte e dermatite granulomatosas associadas a Curvularia sp. em um equino: relato de caso]

Infecções fúngicas traqueais em equinos são raras. Este relato de caso descreve condutas clínicas e cirúrgicas em uma égua com infecção por Curvularia sp. na traqueia e na pele, causando granulomas intraluminais severos e nódulos cutâneos, respectivamente. O animal foi tratado com sucesso com itraconazol e exérese cirúrgica.

Palavras-chave:

Figure 1
18-month-old filly referred for severe dyspnea. Nodules were scattered throughout the body. Circular, elevated, and alopecic nodules are shown on the pinna (A) and near the left ischial tuberosity (B).

Thumbnail

Figure 2
Latero-lateral radiographic projection of the cervical region of the filly, whose trachea was obstructed along its entire length by masses of various diameters.

Thumbnail

Figure 3
Appearance of section of cutaneous nodule collected from the left ischial tuberosity and sent for histopathological and microbiological analysis.

Thumbnail

Figure 4
Gray to black colonies obtained from fungal culture, from samples of skin and trachea, indicating that infection was caused by dematiaceous (pigmented) fungi, phaeohyphomycosis (A). Microscopy of this material showed curved conidia, structurally similar Curvularia sp. (B and C).

Thumbnail

Figure 5
Latero-lateral radiographic projection of the cervical region of the filly after two months of itraconazole therapy. Note regression of the rostral granulomas and improvement in the cartilaginous tracheal rings. The diameter of the largest granuloma is also decreased.

Thumbnail

Figure 6
Appearance of the largest intraluminal granuloma in the trachea, closely adhered to the cartilages, which were thick and deformed, during the tracheotomy procedure for excision (arrows, figure A). Tracheal mucosa after extirpation of the remaining granulomatous tissue, before tracheal suture (B).

Figure 7
Latero-lateral radiographic projection of the cervical region of the filly three months post-surgery. After five months of systemic itraconazole therapy, the tracheal rings remained thick and irregular, but air passage was not compromised.
