Comparison of Immunostaining with Hematoxylin-Eosin and Special Stains in the Diagnosis of Cutaneous Macular Amyloidosis.

Cureus 2020 Apr 9;12(4):e7606. Epub 2020 Apr 9.

Dermatopathology, Molecular Dermatology Research Center, Shiraz University of Medical Sciences, Shiraz, IRN.

Background Although macular amyloidosis is a relatively rare disease, it is a common cutaneous disease in Asia and the Middle East. On hematoxylin and eosin (H&E) stained slides, early lesions could easily be missed without the use of special stains and/or immunohistochemistry. Methods We enrolled 42 patients with the clinical impression of macular amyloidosis who had undergone two 4-mm punch biopsies from 2015 to 2016 at a dermatology clinic affiliated to Shiraz University.

Department of Dermatology, Chapel Allerton Hospital, Leeds, United Kingdom.

Primary localized cutaneous amyloidosis is a group of rare conditions where amyloid deposition is limited to the skin without systemic manifestations. Most cases are sporadic; however, mutations in the oncostatin M receptor (OSMR) and interleukin-31 receptor A (IL31RA) genes can cause a familial form of the condition in up to 10% of cases. Here, we describe a family in which 8 female individuals are affected by either macular amyloidosis or amyloidosis cutis dyschromica. Read More

Amyloidosis is a disorder characterized by extracellular fibrillar deposits of misfolded proteins. The amyloid deposits commonly contain several non-fibrillar proteins as amyloid-associated proteins, but their roles in amyloidosis pathology are still unknown. In mouse senile amyloidosis, apolipoprotein A-II (ApoA-II) forms extracellular amyloid fibril (AApoAII) deposits with other proteins (AApoAII-associated proteins) in many organs. Read More

As a part of the central nervous system, the retina may reflect both physiological processes and abnormalities related to pathologies that affect the brain. Amyloidosis due to the accumulation of amyloid-beta (Aβ) was initially regarded as a specific and exclusive characteristic of neurodegenerative alterations seen in the brain of Alzheimer's disease (AD) patients. More recently, it was discovered that amyloidosis-related alterations, similar to those seen in the brain of Alzheimer's patients, also occur in the retina. Read More

Dysesthesia is a generic term for a cutaneous symptom--such as pruritus, burning, tingling, stinging, anesthesia, hypoesthesia, tickling, crawling, cold sensation, or even pain--without a primary cutaneous condition in a well-defined location that is often caused by nerve trauma, impingement, or irritation. There are multiple types of dysesthesias depending on the body location and the nerves involved. While location, exact symptoms, and etiologies might vary, the underlying theme is that these conditions are of neurologic origin and have dermatologic consequences. Read More

Macular amyloidosis complicating macroprolactinoma--a novel clinical association.

Endokrynol Pol 2015 ;66(6):555-8

Department of Endocrinology Post Graduate Institute of Medical Education&Research (PGIMER) and Dr. Ram ManoharLohia (RML) Hospital, New Delhi 110001, India.

Amyloid deposition in the pituitary gland is a rare localised form of amyloidosis, and most commonly reported with prolactinoma. Macular amyloidosis is a rare form of localised cutaneous amyloidosis of obscure aetiology. In contrast to most localised amyloidosis, the precursor protein(s) of both macular amyloidosis and prolactinoma are unknown. Read More

Nodular amyloidosis derived from keratinocytes: an unusual type of primary localized cutaneous nodular amyloidosis.

Am J Dermatopathol 2015 Nov;37(11):e129-33

Departments of *Pathology, and †Orthopedics, University of Massachusetts Medical School, Worcester, MA.

Primary, localized cutaneous amyloidosis includes macular, lichen, and nodular (tumefactive) types in which the amyloid deposits are limited to the dermis without systemic involvement. The material in lichen and macular amyloidosis is derived from epidermal keratinocytes [keratinocyte-derived amyloid (AK)], whereas that in nodular amyloidosis is derived from immunoglobulin light-chains amyloid (AL). Primary, localized cutaneous nodular amyloidosis (PLCNA) is a form of primary, localized cutaneous amyloidosis that has been associated with a risk of progression to systemic amyloidosis. Read More

β-amyloidopathy in the Pathogenesis of Age-Related Macular Degeneration in Correlation with Neurodegenerative Diseases.

Adv Exp Med Biol 2016 ;854:119-25

Department of Histology, Embryology, Cytology, Volgograd State Medical University, 49 Universitetskiy pr, app 149, 400011, Volgograd, Russia.

Involvement of new biotechnology and genetic engineering methods to the study of the aging organism allowed to select a group of neurodegenerative diseases (NDD) which have a similar mechanism of pathogenesis including pathological processes of protein aggregation and its deposition in the structures of nerve tissue. The development of eye and brain from one embryonic germ layer, community of ethiopathogenetic and morphological manifestations of age-related macular degeneration (AMD) and Alzheimer's disease (AD), a common pathway of β-amyloid precursor protein (APP) are associated with the pathological aggregation of fibrillar β-amyloid (Aβ) protein and the development of β-amyloidopathy in structural elements of the eye and the brain. The review demonstrates the keynote of AMD and AD pathogenesis is β-amyloidopathy that is a manifestation of proteinopathy leading to cytotoxicity, neurodegeneration and the development of pathological apoptosis activated by the formation of intracellular Aβ.

[Beta-amyloidopathy as a manifestation of proteinopathy in age-related macular degeneration].

Vestn Oftalmol 2015 Mar-Apr;131(2):26-31

Volgograd State Medical University, 1 Pavshikh Bortsov Sq., Volgograd, Russian Federation, 400131.

Aim: To investigate clinical and morphological features of amyloidogenesis in age-related macular degeneration (AMD), which is thought to be associated with proteinopathy, namely beta-amyloidopathy.

Material And Methods: A total of 111 eyes with morphological signs of AMD as well as brain samples from 56 cadavers (aged at death 60 and over) were assessed with selective methods of amyloid detection.

Results: Amyloid deposits were present in 39% of eyes with dry AMD and 80% of eyes with wet AMD. Read More

Currently Used Biologic Agents in the Management of Behcet's Syndrome.

Curr Med Chem 2015 ;22(16):1976-85

Cerrahpasa Tıp Fakultesi, Ic Hastalıklari Anabilim Dali, Romatoloji Bilim Dali, 34089, Cerrahpasa, Istanbul, Turkey.

Behcet's s yndrome (BS) is a multisystem vasculitis with frequent mucocutaneous, joint, eye and visceral organ involvement. From early 2000s, biologic drugs have been increasingly used in the management of BS, enabling rapid and complete remission in most cases with critical organ involvement. Despite the current experience with steroids and traditional immunosuppressives, biologics are exceptionally promising for treatment of resistant cases. Read More

A familial poikiloderma-like cutaneous amyloidosis.

Indian J Dermatol 2014 Nov;59(6):633

Department of Dermatology, S. Nijlingappa Medical College, Bagalkot, Karnataka, India.

Familial poikiloderma-like cutaneous amyloidosis(FPLCA) is a rare, generalized but genetic dyschromic skin disorder characterized by amyloid deposits in dermis due to defective DNA repair secondary to sunlight damage. Clinically, it presents with diffuse brownish pigmentation with hypo-pigmented macules and many brownish scattered lichenoid papules with normal developmental milestones. The condition is autosomal dominant with incomplete penetrance. Read More

J Pak Med Assoc 2014 May;64(5):579-82

Primary localized cutaneous amyloidosis (PLCA) is caused by the extracellular deposition of amyloid material in the skin without other cutaneous or systemic organ involvement.
