Tuberculous dacryoadenitis in a child.

BACKGROUND

Orbital tuberculosis is rare even in endemic areas. The disease may involve soft tissue, lacrimal gland, or the periosteum or bones of the orbital wall.

CASE: We present an Indian girl, who presented with a slowly growing left-sided superotemporal orbital mass, with no significant previous medical history. The swelling turned to an abscess and burst spontaneously giving rise to a discharging sinus. The discharge was negative for any organism on Gram and Giemsa staining. A tuberculin skin test was strongly positive. Incisional biopsy showed caseating granuloma and Langhan 's giant cells suggestive of tubercular aetiology. The patient responded well to tuberculous chemotherapy.

CONCLUSION

Although tuberculous dacryoadenitis is a very rare manifestation of tuberculosis,still the possibility should be entertained in a slowly growing mass of the lacrimal gland, especially in developing countries where the prevalence of tuberculosis is high.
