In several families, multiple endocrine neoplasia type 2A (MEN 2A) has been found in association with cutaneous lichen amyloidosis. It has been debated, however, whether the skin amyloidosis found in MEN 2A families, localized exclusively in the interscapular area, represents the same anomaly as that found in autosomal dominant familial cutaneous lichen amyloidosis, which is more generalized. W...

Amyloidosis is induced by deposition of amyloid proteins in various organs. Both systemic and localized type amyloidosis present with a variety of skin manifestations. Based on biochemical and immunological aspects, amyloid proteins are subdivided into several subtypes from different origins. Amyloid fibrils in primary and multiple myelomaassociated systemic amyloidosis are composed of immunogl...

BACKGROUND Primary localized cutaneous amyloidosis (PCA) is a relatively rare condition characterized by amyloid deposition in dermis without systemic involvement. Although, histopathological examination of the lesion reveals amorphous eosinophilic deposits in papillary dermis examination of congo red stained slides under polarized light will give definitive diagnosis AIMS To study the clinic...

Primary cutaneous amyloidosis is limited to the skin without involving any other tissue. Nodular amyloidosis is rare, and atrophic nodular cutaneous amyloidosis is even rarer. We describe the fourth case of atrophic nodular cutaneous amyloidosis by searching PubMed databases. A 52-year-old female presented to our hospital with a 2-year history of orange papules and nodules without subjective sy...

BACKGROUND Cutaneous amyloidosis has been classified into primary cutaneous amyloidosis (PCA, OMIM #105250), secondary cutaneous amyloidosis and systemic cutaneous amyloidosis. PCA is the deposition of amyloid in previously apparent normal skin without systemic involvement. Amyloidosis cutis dyschromica (ACD) is a rare distinct type of PCA. Here, the unique clinical and histological findings of...

LFT: liver function test PLCNA: primary localized cutaneous nodular amyloidosis INTRODUCTION Amyloidosis is a group of conditions that involve the deposition of amyloid proteins in various tissues. It is generally classified as either systemic or cutaneous. Primary localized cutaneous nodular amyloidosis (PLCNA) is the rarest form of cutaneous amyloidosis with the amyloid depositing in the derm...

Localized cutaneous amyloidosis is a rare disease among white people, being more common in South-Asia, China and South America. The disease is characterized by deposition of amyloid material in the papillary dermis without visceral involvement. Nevertheless, there is a growing list of immune-mediated disorders that have been linked to cutaneous amyloidosis. We present two cases of concomitant o...

Primary localized cutaneous amyloidosis is a skin-limited amyloidosis that does not involve internal organs. It is clinically subclassified into 3 general categories and some rare variants. However, there is considerable overlap within the classification. Though there are a variety of therapeutic measures, the treatment is often unsatisfactory, particularly when the disease is severe and extens...

National Skin Centre, 1 Mandalay Road, Singapore 308205 Primary cutaneous amyloidosis is a chronic pruritic disorder with characteristic amyloid deposits in the papillary dermis. The manifestations of primary localised cutaneous amyloidosis (PLCA) are usually confined to the skin. The aetiopathogenesis of PLCA has not been clearly elucidated. We report a patient who developed PLCA after a short...

Objective: To evaluate and assess patients with primary cutaneous amyloidosis with regard to sex, age and clinico-pathologic features in the local population. Design: Retrospective case study. Setting: Social hygiene clinic in Tuen Mun, New Territories, Hong Kong. Patients: Chinese patients with a clinical +/histological diagnosis of primary cutaneous amyloidosis: lichen amyloidosis and macular...
