1. What is Lichen Planus Pigmentosus?

Lichen Planus Pigmentosus, also known as Lichen Planus Pigmentosus-inversus or Lichenoid Melanodermatitis, is a pigmentary disorder of the skin. It is non-contagious and typically affects areas exposed to the sun, such as the face, neck, and forearms. Lichen Planus Pigmentosus can affect individuals of various age groups. However, it is more commonly observed in adults, typically between the ages of 30 and 60. It can occur in both men and women and is more prevalent in people with darker skin types, such as those of South Asian, Middle Eastern, and Latin American descent. While it is less common in children and the elderly, Lichen Planus Pigmentosus can still occur in individuals outside the typical age range.

The lesion first appears on the flexor aspect of upper or lower limbs, over th axillae and on the abdomen , forearms, wrists, legs, genitalia and on the face symmetrically. The typical lesion consists of polygonal and pleomorphic papules which are very small (1-4mm) at the outset but gradually become of the size of a pea with a violet colour. Papules may enlarge with clearing of the centre called “Wickhan’s striae“ and the characteristic shiny waxy appearance may also be seen. The mucous membrane is involved in about 25% of cases. The tongue , lips , penis, vulva, vagina or genital area male and female both may also be involved. In these sites bluish whites patches are seen. Moderate to service itching is always present.

The exact cause of Lichen Planus Pigmentosus is still unknown, but various factors may contribute to its development. Noerbous and mental tension or trauma may predispose. In association with myasthenia gravis with thymoma, graft versus host disease , hepatitis C, drugs like Sulphonamides, Quinacrine, Antimony lichen planus like lesion is seen . This has been seen after exposure to colour film developing solution.

2.1 Genetics Predisposition:

There may be a genetic predisposition, as LPP tends to run in families.

2.2 Autoimmune Reactions :

Like lichen planus, LPP is thought to have an autoimmune component, where the body’s immune system mistakenly attacks healthy skin cells.

2.3 Environmental Triggers:

Certain environmental factors, such as exposure to certain chemicals or allergens, might trigger the onset of LPP in susceptible individuals.

2.4 Viral Infections:

Some studies have suggested a possible link between LPP and certain viral infections, although more research is needed to establish a definitive connection.

2.5 Hormonal imbalances :

hormonal imbalances are believed to be one of the potential causes of Lichen Planus Pigmentosus (LPP). While the exact cause of LPP is not fully understood, it is thought that changes in hormone levels may play a role in triggering or exacerbating the condition.

Hormonal imbalances can occur due to various factors, such as changes during pregnancy, menopause, or fluctuations in hormonal levels related to certain medical conditions. These imbalances may lead to an altered immune response, which can contribute to the development of Lichen Planus Pigmentosus.

However, it’s essential to note that hormonal imbalances are just one of several factors that may be associated with LPP. The condition is likely to have a multifactorial origin, involving a combination of genetic predisposition, environmental triggers, and immune system abnormalities.

2.6 Chronic sun exposure :

Chronic sun exposure is considered to be one of the potential causes of Lichen Planus Pigmentosus (LPP). Prolonged and repeated exposure to the sun’s ultraviolet (UV) rays can lead to skin damage and trigger inflammatory responses in susceptible individuals, potentially leading to the development of LPP.

UV rays can damage the skin’s DNA and activate the immune system, causing an abnormal immune response. In individuals with a genetic predisposition to Lichen Planus Pigmentosus, this aberrant immune response may manifest as the characteristic dark brown to gray-brown patches on the skin.
