Calcinosis cutis is a rare condition characterized by the deposition of insoluble calcium salts in the skin and subcutaneous tissue. Dystrophic calcinosis cutis appears as a result of local tissue damage or abnormalities, such as alterations in extracellular matrix proteins or subcutaneous tissue with normal calcium and phosphate serum levels. It has been rarely described as a late complication...

OBJECTIVE: To report a rare case of a child with essential primary Cutis verticis gyrata. REPORT: Nine-year-old boy with extensive hypertrophy of scalp skin, with a cerebriform appearance. No underlying neurologic and ophthalmologic disorders were found, and no other cases were described in his family.

the authors describe two interesting and seldom cases of atrophia gyrata j and believe it to be a congenital hereditary disease with a recessive character. like retinitis pigmentosa, it does not affect the central posterior parts of the retina but the lesions are around the periphery. the visual fields are narrowed. they discuss; the similarity of this disease with atrophia gyrata described by ...

Onset of the disease is often during the second year of life: there is progressive cerebellar ataxia (initially truncal, with further peripheral extend); ataxia is a constant feature in this disease; oculomotor apraxia, dysarthria, and dystonia; leading to muscular atrophia. Telangiectasia: facial region exposed to sunlight, and eyes (conjunctiva). Combined immunodeficiency (in 70 %): thymus hy...

The spider family Mysmenidae is reported from Vietnam for the first time. Both sexes of three new species are described: Calodipoena tamdaoensis n. sp. from Tam Dao National Park, Gaoligonga taeniata n. sp. and Mysmena maculosa n. sp. from Cuc Phuong National Park. Morphological descriptions, diagnoses and comparative illustrations are provided.

A new genus Luculentsalda Zhang, Yao & Ren gen. nov. (type-species Luculentsalda maculosa Zhang, Yao & Ken sp. nov.) of Saldidae is described and illustrated. All the specimens were collected from Early Cretaceous Yixian Formation of Huangbanjigou, Beipiao City, Liaoning Province, China. New findings suggest that the subfamily Chiloxanthinae probably originated in the eastern part of Laurasia.

The most widely accepted classification of calcinosis cutis is reviewed and several aspects of it are examined. The main point of our criticism is that entities from different groups overlap. Also, the classification mixes etiopathogenic criteria with morphological or semiologic ones. Moreover, the role of the dermatopathologist is limited many times, since only generic information under the di...

Amyloidosis cutis dyschromica (ACD) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. Here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. Five other members of her family are also involved. Biopsy of hyperpigmented lesions revealed increase of melanin in the basal layer, pigment incontinence and amorpho...
