Calcinosis cutis, a rare disorder caused by an abnormal deposit of calcium phosphate into the skin, is observed in a variety of disorders. Peculiar conditions feature skin calcifications in children and may have an iatrogenic origin. The unusual case of a baby showing periodic transepidermal elimination of calcified nodules from her fingertips is reported. In this case, fingertip calcinosis cutis was probably caused by ischemic damage due to the venous obstruction that occurred during intensive care in the neonatal period. 相似文献

Milia-like idiopathic calcinosis cutis 总被引:1,自引:0,他引:1

Milia-like idiopathic calcinosis cutis is a rare entity. Only 17 cases have been reported so far. Two-thirds of these have been associated with Down syndrome. We report the fifth case occurring in a child without Down syndrome. Milia-like idiopathic calcinosis cutis has long been regarded as a peculiar subtype of idiopathic calcinosis cutis. The pathogenesis of the disorder remains unclear. 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

Lupus erythematosus and calcinosis cutis 总被引:2,自引:0,他引:2

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

Calcinosis cutis is a rare disease characterized by deposition of insoluble calcium salts in the skin. Subepidermal calcified nodule is a form of idiopathic calcinosis cutis that commonly affects children but rarely presents at birth. Herein we describe a healthy 10-month-old boy who had a solitary hard nodule on the left foot since birth. Surgical excision of the nodule was done and histopathology confirmed the diagnosis of subepidermal calcified nodule. 相似文献

Pseudoxanthoma elasticum (PXE) is a genetic disorder in which elastic fibers become calcified with prominent cutaneous, ocular, and cardiovascular features. Calcinosis cutis is an acquired disorder of calcium deposition in cutaneous tissues that occurs as one of the following forms: dystrophic, metastatic, idiopathic, and iatrogenic. We report a case of a woman with PXE who developed widespread dystrophic calcinosis cutis in areas affected by PXE. Although tumoral calcification and nephrolithiasis have been reported in patients with PXE, only one other case in the English-language literature of PXE and calcinosis cutis has been reported and this case was characterized by small, milia-like papules on the front of the neck, without significant discomfort, whereas our patient had widespread involvement that was very painful and pruritic. On 6-month follow-up, this patient had only mild improvement after treatment with an anti-itch lotion and aluminum hydroxide, with which she was noncompliant. 相似文献

A case of calcinosis cutis is presented in a patient with hypercalcemia of unknown etiology. The axillae and inguinal areas were involved and the clinical and histologic picture is compared with pseudoxanthoma elasticum. We propose that the similarities between the two diseases stem from a common origin in damaged elastic fibers. 相似文献

Iatrogenic calcinosis cutis following nadroparin injection 总被引:2,自引:0,他引:2

Accumulation of calcium in the skin is usually classified as a group of disorders referred to as calcinosis cutis. We report the case of a patient who developed iatrogenic calcinosis at the site of subcutaneous administration of low-molecular-weight heparins (LMWH) as nadroparin. This is usually used for the prevention of deep venous thrombosis, especially following renal transplantation. The role of calcium content in nadroparin is discussed. 相似文献

Congenital calcinosis cutis is a relatively rare event. Herein we report 3 cases of congenital calcinosis cutis that all appeared in the exact same location on the ear. A possible mechanism of pathogenesis is discussed. 相似文献

Calcification of the penis, whether in the skin, subcutaneous tissue or corpora is exceedingly rare and is usually secondary to trauma or Peyronie's disease. A case of idiopathic calcinosis cutis of the penis is presented. 相似文献
