Laryngeal and ocular granulation tissue formation in two Punjabi children: LOGIC syndrome.

Two unrelated children, both born in the United Kingdom of Punjabi Muslim parents, developed within months of birth, nodules in the larynx, conjunctiva and nailbeds. Currently the younger female child, aged five, is developing skin papules while the elder boy, now aged 15, is debilitated by oral, oesophageal and tracheal granulation tissue formation. Numerous biopsies of the affected tissues have revealed subepithelial granulation tissue formation of unknown aetiology. Extensive haematological, biochemical and bacteriological investigations were uninformative as to the cause. Treatment with steroids, dapsone, antituberculous drugs, and local excision failed to control the disease. No description of this condition exists in the international medical literature available to us.
