Lichen scrofulosorum with tuberculous dactylitis.

A patient with tuberculosis of cervical lymph nodes, lichen scrofulosorum on the trunk and limbs and tuberculous dactylitis of the hands is reported. Both the clinical and histological features of her lichen scrofulosorum conformed to the characteristic pattern described in other recently reported cases and the association with extra-pulmonary tuberculosis was again evident. There have been no other recent reports of tuberculous dactylitis, which was always said to be due to underlying tuberculous bony involvement. In our patient tuberculous dactylitis, which was clinically indistinguishable from previous cases, was found to be due to granulomatous involvement of the overlying skin with no associated bony abnormality.
