Sir,
Dermatology, the science of the skin, was one of the many specialties, which evolved from general internal medicine during the course of the nineteenth century. In India, therapeutics of dermatoses have been known and practised by physicians for centuries. Charaka Samhita contains one chapter on the subject. In this ancient book, worshipful Atreya Punarvasu has described eighteen dermatoses. He attributed these dermatoses to the preponderance of morbid humors (vata, pitta and kapha) causing disturbances of body elements and thereby diseases. [1] There are many legendary dermatologists who had contributed in the field of Indian dermatology. Contributions of Dr. JS Pasricha in contact dermatitis and pulse therapy is remarkable. [2],[3]
We have compiled all signs given by Indian dermatologist. However some of these signs are not globally accepted.
Fountain Sign | | |
This sign is mostly seen in Lichen Planus Hypertrophicus (LPH) lesions of less than 2 years duration. While injecting intralesional steroids by a 26G needle, it has been often found that the medicine comes out through the follicular openings in a jet mimicking a "fountain". [4]
Reverse Namaskar Sign | | |
In patients with Ehlers Danlos syndrome, there is hyperextensibility and fragility of the skin with easy bruisibility due to disorder in collagen. Patients are able to fold the forearms at the back and palms facing each other in a way to do Namaskar. This sign is known as reverse Namaskar sign. [5]
Premlatha Sign | | |
In patients with pemphigus vegetans, there are characteristic cerebriform changes seen on the tongue. Cerebriform tongue, characterized by a pattern of sulci and gyri on the dorsum of the tongue has been reported in up to 50% cases of Neumann type. [6]
Patrick Yesudian Sign | | |
This sign is seen in neurofibromatosis type 1. Multiple melanotic macules of palms with varying size from 2 to 4 mm may be noted in 90% of Indian cases. Fifty cases have been studied in detail and recorded in the world literature in 1984. [7]
Nose Sign (Pavithran's Nose Sign) | | |
It is seen in exfoliative dermatitis in which there is complete absence of erythema and scaling of the nose and perinasal areas. It is hypothesized that sparing of nose in exfoliative dermatitis could be due to greater sun-exposure of nose or it could be explained by the mechanism of island of normal skin. [8]
Hanging Curtain Sign | | |
It is seen in patients with pityriasis rosea. When the skin is stretched across the long axis of the herald patch, the scale is noted to be finer, lighter, and attached at one end, which tends to fold across the line of stretch. [9]
