Soft tissue calcification is known to occur in dermatomyositis, systemic scleroderma and CREST syndrome, but rarely in systemic lupus erythematosus (SLE). Diffuse soft tissue calcifications have not been reported in discoid lupus erythematosus (DLE). In a patient with discoid lupus erythematosus, calcinosis cutis developed about 20 years after the onset of the disease. During the follow-up time of 25 years, manifestations suggestive of a systemic disease were observed in our patient. However, no specific diagnosis could be established. The clinical, light and electron microscopic as well as immunohistochemical findings of our patient are reported. On the basis of electron microscopic findings it is suggested that intracellular calcification occurred in this case. 相似文献

A newborn girl had typical "blueberry muffin" skin lesions, which showed histopathologic features of myelomonocytic leukemia cutis. We could not demonstrate leukemic infiltration of bone marrow in four aspirates. Her course was complicated with primary pulmonary hypertension, which led to death at 7 months of age. We emphasize the persistence of skin lesions in the absence of bone marrow infiltration by leukemia throughout the course of the disease. 相似文献

Concurrent chronic lymphocytic leukemia cutis and acute myelogenous leukemia cutis in a patient with untreated CLL 总被引:1,自引:0,他引:1

Patients who have chronic lymphocytic leukemia (CLL) are known to have a high frequency of second malignant neoplasms. However, acute myelogenous leukemia (AML) occurring concurrent with or after a diagnosis of CLL is extremely rare. In this article we report a case of AML developing in a 55-year-old male with a 6-year history of untreated CLL. The diagnosis was facilitated by touch preparation of a skin punch biopsy specimen. The patient presented with a two-week history of fever, weakness, anasarca, and a skin rash. Physical examination revealed pink to skin-colored firm papules, which coalesced into indurated plaques on his trunk, upper extremities, and face. The lesions, in combination with generalized edema, produced a leonine facies. Touch prep of the biopsy showed medium to large blasts, large monocytoid cells, and numerous small mature lymphocytes, providing the preliminary diagnosis of a second, previously undiagnosed myelomonocytic malignancy in this patient. The initial diagnosis was subsequently confirmed by histologic, cytochemical, immunohistochemical and flow cytometry studies. This is the first reported case of CLL with concurrent AML in which rapid touch prep of a skin punch biopsy facilitated diagnosis. 相似文献

Nanobacteria and calcinosis cutis 总被引:4,自引:0,他引:4
Morgan MB 《Journal of cutaneous pathology》2002,29(3):173-175
BACKGROUND: The nanobacteria are a recently characterized group of extremely small bacteria capable of precipitating calcium salts implicated in the pathogenesis of urinary calculi and calcific atherosclerosis. The pathogenesis of calcinosis cutis and its significance in conjunction with a variety of unrelated scarring and pre-existing cutaneous entities are incompletely understood. METHODS: A series of cases, including basal cell carcinoma with dystrophic calcification, subepidermal calcified nodule, pilomatricoma, and tumoral calcinosis, were ultrastructurally examined for the presence of Nanobacteria sp. RESULTS: All cases, including three basal cell carcinomas, two subepidermal calcified nodules, three cases of pilomatricoma, and two cases of tumoral calcinosis, were negative for Nanobacteria. CONCLUSIONS: The dystrophic calcification that occurs in conjunction with the above entities does not likely involve a bacterial-induced etiology. The cause of these entities remains unknown. 相似文献

Calcinosis cutis is the deposition of insoluble calcium salts in the skin and subcutaneous tissue. We report the case of a 28-year-old Caucasian woman with cystic fibrosis in whom strikingly symmetrical and reticulate calcinosis cutis developed on the lower extremities, which was noted on histology to spare the eccrine glands. Careful review of the literature fails to reveal any previous report with these remarkable cutaneous and histologic manifestations. 相似文献

Spontaneous regression of aleukemia congenital leukemia cutis 总被引:1,自引:0,他引:1

A full-term 2-week-old boy was referred to the pediatric dermatology clinic with numerous blue to violaceous nodules present since birth. TORCH titers (against toxoplasmosis, cytomegalovirus, herpes simplex virus, rubella, and syphilis) were negative. Complete blood count and peripheral smear were normal. A skin biopsy specimen showed an atypical cellular infiltrate suspicious for leukemia or lymphoma. A bone marrow biopsy specimen demonstrated acute myelogenous leukemia (M4 subtype). Following consultation with pediatric oncology and the recognition of the potential for spontaneous regression, chemotherapy for the infant's condition was not recommended. He remained otherwise healthy and was followed-up with biweekly to monthly complete blood counts and physical examinations, which were repeatedly normal. By 3 months of age, the nodules had completely resolved and there was no evidence of recurrence at 8 months of follow-up. We report this instance of aleukemic congenital leukemia with spontaneous regression of leukemia cutis without therapeutic intervention. 相似文献

Calcinosis cutis is a common clinical feature of dermatomyositis and scleroderma but is only rarely reported in association with systemic lupus erythematosus (SLE). We describe three patients with long-standing systemic lupus erythematosus in whom extensive calcinosis cutis developed. We identify characteristics our patients share in common with 23 previously described patients. 相似文献

Dystrophic calcinosis cutis is known to be associated with various connective tissue disorders but to the best of our knowledge has never been reported in subacute cutaneous lupus erythematosus (SCLE), a distinctive cutaneous subset in the spectrum of lupus erythematosus. It occurs without calcium and phosphorus metabolic abnormalities and may be localized or generalized. We report a patient with SCLE who developed calcinosis cutis and had normal serum calcium and phosphorus levels and, interestingly, a normal concentration of blood ionized calcium. This latter, which represents the active form in the total amount of blood calcium, is a parameter only rarely assessed in patients with dystrophic calcinosis cutis. Thus, other pathogenic factors should be investigated to clarify the pathophysiology of the dystrophic type of calcification. 相似文献

We present a unique case of an infant with acute monocytic leukaemia who presented at birth with multiple rubbery, erythematous to violaceous subcutaneous nodules secondary to leukaemia cutis. As these infiltrates regressed with chemotherapy, numerous white to yellow linear confluent papules appeared in a scratch-like pattern. These lesions were widely disseminated but were concentrated across her face, trunk and extremities with relative sparing of the napkin area and back. We propose that these lesions represent a form of dystrophic calcinosis cutis that occurred secondary to koebnerization in an infant with congenital leukaemia cutis. 相似文献
