The spin angular momentum (AM) of a light beam appears due to presence of circular or elliptic polarization. Its characterization is coupled with some paradoxical features which are commonly recognized but, to our opinion, are not satisfactorily explained in the known literature. Namely, for a spatially-homogeneous circularly polarized beam, the spin AM density is zero at every point of the bea...

Plasmoacanthoma and plasma cell cheilitis are rare disorders of obscure etiology characterized by a plasma cell infiltrate. An 80-year-old woman presented with a verrucous, fleshy, skin colored plaque over lips, gingiva, and the palate and painful swallowing for over a period of 6 months. Histopathology of the lesion showed dense infiltrate of plasma cells. The lesions resolved completely after...

Granulomatous cheilitis is a chronic granulomatous inflammatory condition involving the lips with a multifactorial etiology. The difficulty in treatment of granulomatous cheilitis is reflected in various treatments that have been tried and the lack of consensus regarding the preferred treatment. Combined therapy of intralesional corticosteroid and clofazimine or dapsone is one of the most commo...

INTRODUCTION Factitious cheilitis is a chronic condition characterized by crusting and ulceration that is probably secondary to chewing and sucking of the lips. Atopy, actinic damage, exfoliative cheilitis, cheilitis granulomatosa or glandularis, contact dermatitis, photosensitivity reactions and neoplasia should be considered in the differential diagnosis of crusted and ulcerated lesions of th...

Lupus erythematosus (LE) is an autoimmune disease which may initially present solely with lip lesions. Due to a wide spectrum of presentation, these features may initially be misdiagnosed as other oral diseases such as lichen planus, erythema multiforme (EM), and actinic cheilitis, leading to a delay in diagnosis and treatment. We discuss a case of severely crusted cheilitis which was initially...

Cheilitis granulomatosa is characterized by recurrent or persistent swelling of one or both lips. The exact etiology is not certain. It may represent oral manifestations of Crohn's disease and sarcoidosis, so the complete diagnostic work up of the patient with suspected Cheilitis granulomatosa is a must. Microscopically, a non-necrotizing granulomatous inflammation is the typical feature. Manag...

BACKGROUND Plasma cell cheilitis is an unusual benign plasma cell proliferative disease of an unknown etiology that typically presents on the lip. OBJECTIVE The aim of this study was to investigate the clinicopathological characteristics of 13 cases of plasma cell cheilitis. METHODS The present study investigated the clinical manifestations, treatment modalities, and outcome of 13 patients ...
