Lechiguana is a parasitic skin disease of cattle caused by the warble fly Dermatobia spp.

This disease has been reported in southern and southeastern Brazil, in areas where infection by Dermatobia hominis is common[1].

Clinical lesions are characterized by focal proliferative fibrogranulomatous panniculitis[2]. This appears as large, hard, subcutaneous swellings that develop rapidly, mainly in the scapular and adjacent areas (chest, neck, shoulders, and ribs).

Mannheimia granulomatis has been recovered from lesions and is considered causal[3].

Diagnosis is based on presenting clinical signs augmented by histopathologic lesions.

Treatment with chloramphenicol (3 g, sid for 5 days) or danofloxacin (1.25 mg/kg, sid for 3 days) is usually remedial.
