Introduction: Macular amyloidosis is a relatively rare disease. A basic change appears to be amyloid material deposition in an apparently normal skin. The characteristic features of the disease are reticulate and ripple brown pigmentation in interscapular regions. Shoulder, back and chest. There are several reports indicating the association of the disease with rubbing against the skin. Accordi...

Dear Editor, Reticulate pigmentary disorders (RPD) is a term used to classify a spectrum of several acquired and congenital disorders. Different clinical features can be present, including a reticular pattern and a freckle-like pattern with hyperor hypo-pigmented macules (1). Dowling-Degos disease (DDD), an autosomal dominant genodermatosis, is the main type of RPD (2). Clinically, DDD presents...

Erythema ab igne (EAI) is a dermatosis characterised by reticulate red-brown pigmentation and telengiectasia resulting from long-term exposure to infrared radiation. It generally occurs in individuals using heating devices in the winter, those who frequently use hot compresses, and those who prefer hot environments. It generally occurs on the feet of women but may also occur on the hips and thi...

Amyloidosis cutis dyschromica is a rare type of primary cutaneous amyloidosis characterized by reticulate hyper-pigmentation with discrete hypopigmented macules. Up to date, about 50 cases of amyloidosis cutis dyschromica have been reported and the majority are familial cases of Asian ethnicity. Various diseases, particularly autoimmune diseases such as systemic sclerosis and systemic lupus ery...

Dyskeratosis congenita (DC) is characterised by reticulate skin pigmentation, mucosal leucoplakia, and nail dystrophy. Bone marrow failure occurs in 50% of patients and is the principal cause of early mortality. In the majority of families the pattern of inheritance of DC is compatible with an X linked recessive trait. The locus for the X linked recessive form of DC has been linked to Xq28. We ...

Nine patients, seven males and two females aged 6-14 years, presented with extensive, asymptomatic, brown-black macules and mildly elevated, pigmented lesions of a few months' duration. The sites affected were the face, trunk and proximal extremities. The skin lesions were discrete and individual lesions were less than 2 cm in size. The clinical diagnoses rendered by the referring physicians we...

The Halieutichthys aculeatus species complex is reviewed. Members of this clade are distinguished by the presence of tubercles on the tail and a reticulate dorsal pigmentation pattern. Three species are recognized, including two species new to science. A neotype is chosen for H. aculeatus. Halieutichthys bispinosus n. sp. is characterized by having relatively strong tubercles on the dorsal surf...

Dyskeratosis congenita, a rare inherited condition, is estimated to occur in 1 in 1 million people. The disease is characterised by a classic triad: nail dystrophy, reticulate skin pigmentation, and oral leukoplakia. These patients may also exhibit variable extend of pulmonary, gastrointestinal, genitourinary, cerebral, and dental involvement. Early mortality is often associated with bone marro...
