A rare case of trichoadenoma over the vulva.

Trichoadenoma of Nikolowski is a rare, benign, well differentiated, slowly growing tumor of the hair follicle which was first described in 1958 by Nikolowski. It usually occurs as a solitary nodular lesion between 3 and 15 mm in diameter. It commonly occurs on the face or the buttocks.

Vaccines in Dermatology.

A vaccine is a biological preparation that improves immunity to a specific disease. More than two centuries have passed since the first successful vaccine for smallpox was developed. We've come a long way since.

Annular bullous lesions with atypical erythema multiforme in leprosy.

Erythema nodosum leprosum (ENL) is an immune complex-mediated reaction that may complicate the course of multibacillary leprosy. Bullous lesions in Type II reaction, though reported, are exceedingly rare. We report the case of a 32 year old female patient who presented initially at our OPD with erythema nodosum.

Eccrine poroma on the face: an atypical presentation.

An eccrine poroma is a solitary tumor arising from the eccrine duct epithelium in the epidermis. The lesions commonly occur on the sole of the foot, the hands, and occasionally on the nose, eyelids, neck, and chest. We report a patient who presented with a slow-growing nodular lesion over her left cheek, prompting a diagnosis of basal cell carcinoma or keratoacanthoma.

Treatment of facial lesions of multicentric reticulohistiocytosis by carbon dioxide laser.

The carbon dioxide (CO2) laser is a versatile tool that has applications in ablative lasing and caters to the needs of routine dermatological practice as well as the esthetic, cosmetic, and rejuvenation segments. We report a case of multicentric reticulohistiocytosis with cosmetically disfiguring confluent papules over the scalp, forehead, nasolabial folds, chin, and retroauricular region. We used CO2 laser in superpulse mode for ablating the lesions in three sittings.

Rare sweat gland tumors of vulva: Report of two cases.

Syringomas and Fox-Fordyce disease are appendageal skin disorders. While syringomas represent an adenoma of the intraepidermal eccrine duct, Fox Fordyce disease occurs due to blockage of the apocrine sweat duct. In both conditions, extragenital sites are more frequently involved than the genitalia.

Multicentric reticulohistiocytosis.

Multicentric reticulohistiocytosis is a rare systemic granulomatous disease of an unknown cause, characterized by distinct histopathology. The skin, mucosa, synovial, bone, and internal organs may be involved. Cutaneous nodules and distinctive arthritis are the most prominent clinical features.

Post-kala-azar dermal leishmaniasis in HIV-positive patients: A study of two cases.

Cutaneous leishmaniasis and human immunodeficiency virus (HIV) co-infection is emerging as increasingly frequent and serious new disease. Leishmaniasis may be acquired before or after HIV infection. We describe two cases of post-kala-azar dermal leishmaniasis in HIV-positive patients.

Diffuse cutaneous leishmaniasis: co-infection with human immunodeficiency virus (HIV).

Cutaneous leishmaniasis is a disease caused by intracellular protozoal parasites belonging to the genus Leishmania. Immune suppression caused by HIV infection is an important factor for atypical presentation and widespread progression of cutaneous leishmaniasis. Diffuse (disseminated) cutaneous leishmaniasis and HIV co-infection is emerging as an extremely serious new disease.
