To the editor, Melkersson-Rosenthal syndrome (MRS) is characterized by the triad of persistent or recurrent orofacial edema, relapsing facial paralysis and fissured tongue. Its most consistent clinical symptom is recurrent orofacial or lip swelling. Onequarter of MRS patients exhibit the classic triad 1 . The classical histopathological finding is noncaseating epithelioid granulomas. However, absence of these does not exclude the diagnosis. MRS, which has an unknown aetiology, affects primarily young adults. To date, considerable amount of cases of MRS coexistent with psoriasis have been described in the literature 2-5 . In the light of the relevant literature and the case presented here, we discuss the possible association between or coincidence of psoriasis and MRS. A 49-year-old male presented with a 13-year history of progressive and persistent painless swelling of the upper and lower lips. He also gave a history of asymptomatic eruption on his scalp, face, trunk and upper extremities for several months. He had been treated with oral corticosteroids for recurrent lower motor neuron type facial palsy in the preceding four years. The patient was an otherwise healthy man. He did not have any respiratory, gastrointestinal and neurological symptoms. There was no family history of similar complaints and granulomatous disease such as sarcoidosis or Crohn's disease.On examination, the upper and lower lips and, prominently, the right side of the face were swollen (Figure 1a). Erythematous papulosquamous eruption was noted on his scalp, face, trunk and upper extremities (Figure 2a, 2b). There was fissured tongue on oral examination ( Figure 1b). Specimens obtained by incisional biopsy which was performed on the lower lip did not reveal typical granuloma. However, serial sections showed loose granuloma-like histiocyte accumulations (Figure 3a, 3b). The findings of routine blood and stool examination were normal. Chest X-ray did not reveal hilar or mediastinal node enlargement. On the basis of clinical findings, the diagnosis of MRS was made. The biopsy specimen from a plaque lesion on the scalp presented a psoriasiform lesion with parakeratosis and neutrophils in parakeratotic scale. Dermis showed dilated capillaries (Figure 3c). Periodic acid-Schiff staining did not show any fungal organism. The histopathological findings were consistent with psoriasis. Since the diagnosis of MRS is based on typical clinical features, histological evidence is not essential. Noncaseating granulomas in histopathological examination support the diagnosis. The pathologic examination of our patient showed chronic inflammation with focal histiocyte accumulation. He presented with the full triad of the syndrome. The fissured
