(1/11) Cutaneous mucinosis and mastocytosis in a shar-pei.
A 7-year-old shar-pei was presented because of a recurrent dermatologic condition. Skin biopsies revealed an idiopathic (primary) cutaneous mucinosis that initially responded to corticosteroids. The condition reappeared 2 years later and subsequent biopsies revealed a mast cell tumor in some of the skin sites previously diagnosed with mucinosis. (+info)
(2/11) Severe lung involvement in systemic scleromyxoedema: a highly unusual finding.
Scleromyxoedema is a rare systemic disorder characterized by a lichenoid papular rash. Although scleromyxoedema can involve any organ, very few cases of pulmonary involvement have been reported. Moreover, there are no reports in the literature on treatment of this condition, especially with lung transplantation. The authors report a case of scleromyxoedema in a young man with neurological, skin and respiratory involvement, the latter being mainly characterized by pulmonary emphysema. Due to the serious respiratory compromise, and to the stability of the systemic lesions, a bilateral lung transplantation was performed with successful results at 4.5 yrs. In conclusion, lung transplantation may be required in patients with severe respiratory failure caused by scleromyxoedema. (+info)
(3/11) Papulonodular mucinosis in systemic lupus erythematosus.
A 41-year-old man with systemic and serological manifestations of systemic lupus erythematosus presented with a diffuse eruption comprising annular plaques. Histopathology revealed diffuse deposition of mucin throughout the dermis, consistent with papulonodular mucinosis. This uncommon entity of unclear pathogenesis has been described in systemic lupus erythematosus, discoid lupus erythematosus, and subacute cutaneous lupus erythematosus. (+info)
(4/11) Pimecrolimus 1 percent cream and pulsed dye laser in treatment of a patient with reticular erythematous mucinosis syndrome.
We report on the efficacy of twice daily application of pimecrolimus 1 percent cream in a 48-year-old woman with reticular erythematous mucinosis (REM) syndrome and compare its results with pulsed dye laser (PDL) on the other side of her chest and back. The patient was previously treated by hydroxychloroquine but only a fair response was observed. After application of 5 months of pimecrolimus, the lesions completely resolved and the result was comparable with the other side of her body treated by pulsed dye laser PDL. Topical pimecrolimus and pulsed dye laser appear to be effective and safe treatments for REM. (+info)
(5/11) Linear morphea with secondary mucinosis.
(6/11) Hereditary progressive mucinous histiocytosis: first report in a male patient.
(7/11) Brown plaques on the lower back.
A 12-year-old girl presented with a 2-year history of a 10 cm area of asymptomatic brown coalescent plaques of coalescent, linearly arranged papules on the lower back. No other physical or systemic abnormality was detected. Routine laboratory investigations, including thyroid function tests, were normal. The histopathological examination revealed hyperkeratosis, papillomatosis, and elongated rete ridges in the epidermis. On special staining (Alcian blue), mucin deposition was seen in the papillary dermis. The remaining dermis was normal. A diagnosis of Mucinous Nevus was made. (+info)
(8/11) Oral focal mucinosis: a rare case report of two cases.
Oral focal mucinosis (OFM) is a rare soft tissue lesion of unknown etiology. Clinically, it is most commonly found on the gingiva and presents as a painless, sessile or pedunculated mass of the same colour as the surrounding mucosa. Histologically, it is characterized by focal myxoid degeneration of connective tissue. OFM occurs predominantly in adults during the fourth and fifth decade of life, although it has been reported infrequently in children and adolescents. Its diagnosis mainly relies on histological analysis and the treatment involves complete surgical excision. Its recurrence is unreported. The aim of this report of two cases is to describe the clinical and histological presentation and subsequent management of OFM. The cause of OFM remains unknown. The cases presented in this report bring OFM to the attention of anatomical pathologists while considering the differential diagnosis of myxoid lesions of the oral cavity. (+info)
