The disease known as “Lichen planus pigmentosus” (LPP) was first described by Bhutani et al. in 1974. It is characterized by macules of dark brown color distributed primarily in the sun-exposed areas of the body.
Both sexes are susceptible, but women are more likely to develop the disease, which sneaks up on them after the age of 30.
Hyperpigmented lesions appear in sun-exposed or flexural areas of the body in lichen planus pigmentosus, a rare variant of cutaneous lichen planus.
Symptoms
The face and neck are typically the first areas of the body to show symptoms, with the upper extremities and trunk following later.
The oral mucosa and folds like the axillae, inframammary regions, and groin are relatively uncommon sites of involvement.
The initial lesions are small, brown, oval macules with diffuse borders, and they are initially asymptomatic or mildly pruritic.
They eventually blend to form gray or brown pigmented areas.
The pigmentation could be perifollicular, reticulate, or diffuse.
However, they can also appear in segmental, zosteriform, or blaschkoid patterns. The patches are typically distributed symmetrically.
Causes
Several agents have been reported to act as predisposing factors, despite the fact that the etiology is essentially unknown.
The idea that sunlight may be a major etiological agent has been prompted by the prevalence of exposed areas in many patients.
Other hypothesized causes include the hepatitis C virus, amla oil, which may be photosensitive due to fragrances, kumkum, and other cosmetics, mustard oil, which may contain the photosensitizer allyl thiocyanate, and the hepatitis C virus.
Additionally implicated are abnormalities in T-lymphocyte operations.
Gold therapy has the ability to cause it.
Hepatitis C infection, nephritic syndrome, frontal fibrosing alopecia, acrokeratosis of Bazex, circulating antinuclear antibodies, scarring alopecia, and scarring alopecia have all been linked to lichen planus pigmentosus.
Prognosis
Apparently having a chronic nature, lichen planus pigmentosus
HOMOEOPATHIC REMEDIES
When it comes to LPP, there are many effective medicines available in homoeopathy, but the choice depends on the individuality of the patient, taking the patient’s mental and physical health into account. Homoeopathy is a rapidly expanding system that is being practiced all over the world. Its strength lies in its evident effectiveness as it takes a holistic approach towards the sick individual by promoting inner balance at mental, emotional, spiritual, and physical levels.
ANTIMONIUM CRUDUM 30Antimonium crudum is a treatment option for LPP when the patient experiences measles-like eruptions on the dry skin, intense itching that is made worse by heat from the bed, burning and itchy eruptions that are worse at night, and skin that is sensitive to cold bathing.
LACHESIS 0/3—Lachesis is prescribed when the patient experiences symptoms of throat, abdominal, and head constriction, bluish, blackened skin, and bluish purple eruptions.
THUJA OCCIDENTALIS 1000—Thuja occidentalis is effective for LPP with hyperpigmented brown colored spots that are visible on the face, hands, and arms. Skin is extremely sensitive to touch. Itching and burning are violent, and cold bathing makes them worse.
SULPHUR IODATUM 30LPP with papular eruptions on the face, papular eruptions with ongoing itching, and itching on the ears and neck is treated with sulfur iodide.
