  To the Editor, Top

Various causes of oral mucosal pigmentation have been mentioned in the literature. But isolated involvement of tongue only occurs in black hairy tongue,[1] fixed drug eruptions [2,3] and pigmented naevi.[4] History and clinical features substantially differentiate one entity from the other. In none of them other family members are similarly affected. We herein report a case of isolated pigmentation over tongue in a young woman and her daughter.

A 30-year-old female presented with asymtomatic hyperpigmented patches over tongue of 6 months duration. There was no history of preceding drug intake or sensation of swelling and numbness over the tongue. She was otherwise healthy with no history of weakness, diarrhoea or pain abdomen. On examination, multiple ill-defined violaceousblack variably sized patches were noted over dorsum and lateral borders of tongue. There was no papillary hypertrophy, atrophy or erosion over the patches. No similar patch was seen over any other part of oral mucosa, perioral areas, other mucosae and rest of the skin. Systemic examination did not reveal any abnormality.

History and clinical features substantially ruled out the possibilities of Addison's disease, Peutz-Jeghers' syndrome, lichen planus, fixed drug eruption and melanocytic naevi affecting tongue. Further enquiry revealed history of similar hyperpigmented patch over tongue in her 10-year-old daughter. The duration in daughter was 1 year and as in mother other diagnoses were excluded. Thus a diagnosis of 'idiopathic familial hyperpigmentation of tongue' was made. Our case could be avariant of racial mucosal hyperpigmentation[4] affecting the tongue selectively.
