Clinicopathological Study of Primary Cutaneous Amyloidosis in a Tertiary Care Center of Eastern India Reveals Insignificant Association with Friction, Scrubbing, and Photo-Exposure: How valid is the "Keratinocyte Hypothesis"?

Introduction: Primary cutaneous amyloidosis (PCA) can be classified into four principal categories: macular amyloidosis, lichen amyloidosis, biphasic, and nodular amyloidosis. Some unusual variants such as widespread diffuse hyperpigmentation without papules, poikiloderma like involvement, lesions following Blaschko's line, etc., have also been reported.

Topical Steroid Damaged/Dependent Face (TSDF): A Study from a Tertiary Care Hospital in Eastern India.

Background: Awareness against abuse of topical corticosteroids (TC), especially over the face, has been going on for last 5 years in India. In spite of that we are getting lots of cases in our hospitals.

Aims: The aims of this study were to ascertain the demographics, magnitude and clinical features of TC misuse on the face among the dermatology outpatient department (OPD) attendees and to analyze its causes.

Controversies in the Management of Cutaneous Adverse Drug Reactions.

Some cutaneous adverse drug reactions (CADRs) are severe life-threatening conditions due to multisystem involvements with a high morbidity and mortality rates ranging from 25 - 70% and require immediate medical care. But there are huge controversies regarding the management because large clinical trials are lacking. Most frequent discussion and division occur regarding the use of systemic corticosteroid as early intervention with corticosteroids controls inflammation.

Stamping a Case of Cutaneous Adverse Drug Reaction: Proving Beyond Causality Assessment.

Different types of skin testing with a suspected drug have been reported to be helpful in determining the cause of cutaneous adverse drug reactions (CADRs). It is of utmost importance for practicing dermatologists to have a first hand knowledge of different types of skin tests available in a case of CADR. In each suspected case, a detailed investigation with the suspected agent and correlation of the positive skin reaction with clinical variant of CADR is advocated.

Drug Reaction with Eosinophilia and Systemic Symptoms: An Update and Review of Recent Literature.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, is also known as drug induced hypersensitivity syndrome and by various other names. It is now recognised as one of the severe cutaneous adverse reaction (SCAR) and can be potentially life-threatening. Historically, it was most frequently linked with phenytoin and was initially described as phenytoin hypersensitivity syndrome.

Acute Generalised Exanthematous Pustulosis: An Update.

Acute generalised exanthematous pustulosis (AGEP) is a severe cutaneous adverse reaction and is attributed to drugs in more than 90% of cases. It is a rare disease, with an estimated incidence of 1-5 patients per million per year. The clinical manifestations characterised by the rapid development of sterile pustular lesions, fever and leucocytosis.

A clinical rating scale for the assessment of facial aging in Indian population.

Background: Estimation of facial aging has assumed growing importance due to the advent of several antiaging therapies. Evidence-based estimation of global facial aging is often necessary, especially for validation of these treatment modalities. Most available methods are expensive and have been used in fair skinned individuals.

Zinc-responsive acral hyperkeratotic dermatosis-A novel entity or a subset of some well-known dermatosis?

Background: We are reporting a series of interesting cases, which presented to us with psoriasiform lesions distributed over the acral regions of the body. The cases are unusual because they were resistant to conventional treatment modalities like topical corticosteroids, tacrolimus and oral methotrexate but showed significant improvement on oral zinc therapy.

Materials And Methods: Ten patients with characteristic clinical features of distinctive hyperkeratotic plaque in the acral areas, who were resistant to treatment by different modalities including potent topical steroids and oral methotrexate, were included for detailed investigations.

Eccrine angiomatous hamartoma: late onset facial presentation.

Eccrine angiomatous hamartoma (EAH) is a very rare benign neoplastic condition characterized by hamartomatous proliferation of eccrine glands and accompanying blood vessels and lymphatics. These lesions are more often present at birth or appear during early infancy and childhood and present as solitary nodule or plaque with occasional pain and sweating. They are generally present on the extremities, mostly the palms and soles.

A case of ichthyosis hystrix: unusual manifestation of this rare disease.

Ichthyosis hystrix is a term used to describe an ichthyosiform dermatosis which is characterized by hyperkeratotic spiny scales mainly over extensor aspects of limbs with palmoplantar keratoderma and occasionally associated with deafness and neurological deficit. It is a rare autosomal dominant form of ichthyosis and very few cases are reported in literature. We are presenting a 46 years-old-male patient of ichthyosis hystrix with unusual presentation.

Ichthyosiform large plaque parapsoriasis: report of a rare entity.

Large plaque parapsoriasis (LPP) is an idiopathic, chronic scaly dermatosis classified within parapsoriasis group of diseases, occurring commonly in middle aged patients of all races and geographic regions. LPP and its variants are closely related to the patch stage of mycosis fungoides. The two types of LPP mostly described are the poikilodermatous and retiform parapsoriasis.

Diogenes syndrome: a case report.

Cessation of normal skin cleansing seen in geriatric or self-neglected patients can cause accumulation of keratinous crusts on the skin. In the extreme end of this spectrum is a condition known as Diogenes syndrome (DS). These patients may have psychiatric disorders like paranoid disorders, mood affection, or temporofrontal dementia.

Keratoacanthoma centrifugum marginatum with atypical scar.

Keratoacanthoma centrifugum marginatum (KCM) is a rare variant of keratoacanthoma (KA). It is characterized by a progressive peripheral expansion and central healing leaving atrophic scar. It is sometimes confused with squamous cell carcinoma (SCC) both clinically and histopathologically.
