Rosacea
Bookmark and Share

Pityriasis rosea is an acute skin eruption of unknown etiology. It seldom occurs in a true epidemic pattern, although occasional familial or household outbreaks may also occurs. There are little proves to show that the disease is actually contagious or infectious.

Symptoms of Rosacea

Rosacea is characterized by the appearance of superficial light red macules or papules. They may be generalized over most of the skin surface, with the exception of the face an hands. It may be localized to certain areas such as the trunk, thighs, axillae or groin. This generalized outbreak is frequently preceded by the appearance of a primary lesion” or herald spot” seven to ten days previously.

This spot is brighter red and larger (3 to 4 cm in diameter) than the multiple eruptions which follow its appearance. The individual exanthematous lesions are commonly ovoid. Their long axis are parallel to the natural lines of cleavage of the skin, and are covered by a thin silvery scale.

The lesions often manifest mild itching. In some cases of Rosacea, it may be accompanied by headache and low grade fever.There may also be observed cervical lymphadenopathy.

Pityriasis rosea usually runs its course in three to six weeks and seldom recurs. It is interesting to know that the disease occurs seasonally. It is much more common in the spring and outumn than at other times. It involves young adults chiefly but shows no definite sex predilection. But in very few cases, there is slight prediminana in women.

The cause of Pityriasis rosea is unknown. But it is mainly thought that it is due to infection and the virus is the causative agent of such infection. It is also thought to be associated with nervous strain or emotional disturbance. But this thing is purely coincidental.

Rosacea Awareness

In the Oral Cavity, there is involvement of the oral mucous membrane. The oral lesions appear either concomitantly with or subsequent to the skin manifestations. They are not present throughout the clinical course of the disease, but are usually prominent during its most severe phase.

The oral lesions usually occur only on the buccal mucosa. But in some cases tongue and palatal lesions may also be observed. The oral lesions commonly appear as erythematous macules with or without a central area of grayish desquamation. The lesions may be single or multiple. Usually they are irregular in shape. Occasionally the lesion shows a raised border and vary in size from a few millimeters to one or two cms in diameter.

These lesions are asymptomatic and are of no clinical significance. They clear simultaneously with the skin lesions. Histrologically, there may be oedema, hyperemia and infiltration of lymphocytes, plasma cells and histiocytes. These all things are prominent in the superficial connective tissue. There may also be sprinkling of leukocytes within the epithelium. The microscopic changes in Rosacea are not patho-gnomonic. But may show slight acanthosis.

Treatment of Rosacea

Rosacea, generally demands no treatment. It is because the disease is self limiting and it generally undergoes rapid, spontaneous regression. Seldom, is the patient’s life endangered but chronic episodic recurrences are disheartening. Moreover, patient doesnot feel psychologically well because of the red spots seen on the body. He/she wishes to get immediate heal up, and that is true too, and it does not shows any pathological as disease causing changes in the tissues.
