Oral Lesions Associated With Pityriasis Rosea

To the Editor.—  Kay et al in the November 1985 issue of the Archives¹ reported on the uncommon observation of ulcerative oral lesions in association with concomitant cutaneous pityriasis rosea. The oral lesions arose several weeks following the primary indication of a papular squamous eruption covering the entire trunk and proximal upper extremities. The oral lesions were characterized as multiple shallow ulcerations with a yellow-gray membrane and a regular border with an erythematous halo. The ulcers were described as aphthouslike in morphology and were distributed on the buccal mucosa, lower lip, palate, and on the ventral surface of the tongue. The latter site is documented in their Fig 4, although it is stated in the legend that this is representative of palatal ulcerations rather than those on the tongue. Indeed, the evidence for any ulceration on the palate is extremely weak in this particular photograph.I wish to submit
