A case report on: extragenital and genital LSA.
CASE REPORT: A 28-years-old man presented with skin lesions on both forearm, both dorsum of hands, involving finger web spaces, on both legs and dorsum of feet for two years. Later these lesions also involved tip of penis, groins, and axilla. Few lesions were also present on abdomen, prepuce and glans, and some on anterior part of scalp. Initially these lesions started as small itchy papule on forearm and dorsum of hands. Later they gradually coalesce in size forming a sclerotic plaque type lesion, ivory white in color with shiny or wrinkled surface with mild itching present occasionally over extra genital lesion. Pain and itching was present over genital lesion. H/o repeated sunburn of skin present, there is no h/o repeated trauma, dysuria, pain on defecation, but pain occur when pt. retract the foreskin of penis. There were no complaints suggestive of any systemic Involvement and also there is no significant family history.
Examination revealed multiple ivory white colored plaque type of lesions, variable in size present over forearm, arm, dorsum of hands, finger web spaces, on anterior part of scalp, in axilla, over legs and dorsum of feet, groins and at the tip of penis. The sclerotic plaques are covered with a fine wrinkled (often referred to as cigarette paper-or parchment -like) epidermis. Routine blood investigations were within normal limits. A skin biopsy was taken with a clinical differential diagnosis of Post inflammatory hypopigmentation, vitiligo, pityriasis versicolor and morphea.
HISTOPATHOLOGY: Microscopic--serial sections studied sections show orthokeratotic stratum corneum covered epidermis with focal thinning and vacolar alteration of the basal layer. Underlying superficial epidermis shows focal band like lymphohistiocytic inflammatory infiltrate. Mild perivascular lymphocytic infiltrate also seen.
DIAGNOSIS: Lichen Sclerosus et atrophicus. (LSA).
DISCUSSION: LSA is a rare, chronic inflammatory dermatitis that affects both the dermis and epidermis. Although the etiopathogenesis is not exactly known, Borrelia infections, hepatitis C infections, genetic factors, and androgen level irregularities are thought to be related.  LSA is more frequently seen in females, and it can occur at any age. The prevalence peaks in the fifth and sixth decades of life, and between the ages of 8 and 13.  Although it is commonly seen in the anogenital area (83-98%), it can be seen in extra genital areas in 15-20% of patients. [4, 5]
Extragenital LSA is most commonly located on the neck, upper arms, and flexor surfaces of the wrist;  however, generalized LSA has not been commonly reported in the literature.  In our case patient has predominantly extra genital lesion covering most of body surface area also with genital lesions.
Extragenital LSA without accompanying genital lesions was recorded in 805 of 4280 cases reviewed by Meffert et al.  LSA is most common on the neck, shoulders, and upper portion of the trunk. It is generally asymptomatic, but occasionally pruritic. Most lesions of extra genital LSA present as flat, white, polygonal papules, and slight atrophic white plaques. 
Phototherapy (UVA1, PUVA), surgery and topical tacrolimus are available for treatment. Generalized LS treatments include phototherapy (PUVA, UVA1), hydroxychloroquine, pulsated systemic corticosteroids, and methotrexate combinations. (3, 8) Our Patient kept over PUVASOL and topical Tacrolimus 0.1% and emollient from last 8 months and shown good response. Which could be seen in photographs (Figure 9 to 12)?
CONCLUSION: This is a case of rare presentation of generalized extra genital LSA and it's association with genital LSA. Diagnosis was made by mainly by clinically and supported by histopathologic findings. Patient has shown good response after treatment with PUVASOL and topical tacrolimus 0.1%.
