Comparison of outcomes of azathioprine, leflunomide and allergen avoidance in patients with patch test-positive pigmented contact dermatitis: a randomized comparative study.

Background: Pigmented contact dermatitis (PCD) is a noneczematous form of allergic contact dermatitis characterized by dermal hyperpigmentation. Allergen avoidance is the cornerstone of therapy, but it is difficult to achieve. The use of immunosuppressives seems rational, but data are lacking.

Case Report: Successful Outcome of Primary Infertility with Multidrug Therapy in a Long-Standing Case of Hypogonadism Resulting from Lepromatous Leprosy: Shattering the Dogma of Irreversible Infertility in Leprosy.

We present a case of primary infertility with features of hypogonadism in a male patient with lepromatous leprosy who had remained undiagnosed for 3 years. On investigation, azoospermia and deranged gonadotropin levels with normal serum testosterone were noted and the patient was initiated on multibacillary-multidrug therapy with the primary aim of treating the disease. Although the cutaneous lesions improved within 6 weeks, remarkably infertility was reversed in 2 months-with concomitant normalization of luteinizing hormone, follicle stimulating hormone, and sperm count-an outcome that was unexpected.

Optical damage limit of efficient spintronic THz emitters.

THz pulses are generated from femtosecond pulse-excited ferromagnetic/nonmagnetic spintronic heterostructures via inverse spin Hall effect. The highest possible THz signal strength from spintronic THz emitters is limited by the optical damage threshold of the corresponding heterostructures at the excitation wavelength. For the thickness-optimized spintronic heterostructure, the THz generation efficiency does not saturate with the excitation fluence even up till the damage threshold.

Griscelli Syndrome Type 3 with Coexistent Universal Dyschromia-An Uncommon Association of a Rare Entity.

Griscelli syndrome type 3 is an autosomal recessive disorder caused by mutations in the melanophilin gene and does not have any mucocutaneous or systemic abnormalities other than a pigmentary dilution of skin and hair. We report a case of an 8-year-old girl who presented with silvery grey hair of scalp, eyebrows, eyelashes, and entire body surface with associated universal dyschromia of the skin. After establishing a definite diagnosis of Griscelli syndrome 3, the prognosis was explained and counseling was given.

Cutaneous Histoplasmosis: An Unusual Presentation with Nasal Obstruction.

Histoplasmosis is a systemic fungal disease that may be presented with a variety of clinical manifestations, usually as an opportunistic infection in immunocompromised individuals. We present an HIV seropositive patient with a large fleshy growth causing left-sided nasal obstruction, as an unusual presentation. The lesions shrunk dramatically and almost completely on intravenous amphotericin-B lipid complex (ABLC) given for 2 weeks followed by long-term oral itraconazole.

Complete Remission in a Patient with Treatment Refractory Bullous Pemphigoid after a Single Dose of Omalizumab.

Bullous pemphigoid (BP) is an autoimmune disorder known to be mediated by immunoglobulin G (IgG) autoantibodies. The role of immunoglobulin E (IgE) antibodies is being investigated as their presence has been described in severe cases. Herein, we report a patient of BP who was refractory to most conventional agents and developed hypotension after rituximab but achieved lasting remission after a single dose of the anti-IgE monoclonal antibody omalizumab.

Non-bullous neutrophilic lupus erythematosus-Muted bullous disease?

Non-bullous neutrophilic lupus erythematosus is a rare form of cutaneous lupus erythematosus (LE). We hereby present a case of 24-year-old female, known case of discoid LE (DLE) with negative ANA stabilized on hydroxychloroquine for 2 years. She reported new occurrence of erythematous, mildly pruritic, papular lesions and painful mucosal ulceration.

Papillary tumor in pineal region: Immunohistochemistry meeting the diagnostic challenge.

Papillary tumor of pineal region (PTPR) is extremely rare and poses diagnostic challenge with other central nervous system tumors having papillary architecture. Immunohistochemistry is crucial for a definitive diagnosis of PTPR.

Lichenoid drug reaction due to anti-tubercular therapy presenting as erythroderma.

First-line anti-tubercular therapy (ATT) is very effective in management of tuberculosis and is usually well tolerated. Varied spectrum of cutaneous adverse drug reactions is associated with ATT, of which lichenoid drug eruption (LDR) constitutes approximately 10% of the cases. However, LDR presenting as erythroderma is very rare.

Reverse Koebner's phenomenon in a case of Lymphohemangioma circumscriptum: A diagnostic clue representative of the Whimster hypothesis.

Background: Lymphangioma circumscriptum are benign hamartomatous lymphatic growths, diagnosed clinically by the morphology of groups of clear fluid filled to serosanguinous fluid vesicles. MRI is an essential investigation to assess the depth of the lesions.

Aim: To report an interesting hitherto unreported observation of Reverse Koebner's phenomenon, which can be used as a new diagnostic technique in Lymphohemagioma.
