In this study the data on 200 patients affected by various features of lichen planus (LP) are reported. All subjects were in-patients of the Department of Dermatology, Bari, from 1973 to 1988. In 87% of cases the disease appeared as
lichen
tuber planus, and in 9% there was involvement of mucous membranes. Equal involvement of sex incidence has been found, and the patients were middle-aged (mean, 47 years). The lesion were not subsided in about 10% of cases. Associated fortuitous skin conditions were mainly alopecia areata and vitiligo. In addition, LP has been observed in association with diabetes (8%) and hepatic diseases (10%). These last values could appear relevant, but in our region, Apulia, both diabetes and
hepatitis
, and especially B-
hepatitis
, are very frequent diseases. Our clinical follow-up did not allow to consider LP as a symptom of other subsequent organic diseases.

A variety of prodromal symptoms of viral hepatitis (urticaria, fever, arthralgias, headache, polyradiculonevritis) are attributed to A, B, C, D or E
hepatitis
only when jaundice appears, and because they disappear with it. Spectacular extrahepatic symptoms (polyarteritis nodosa, cryoglobulinemia, glomerulonephritis, marrow aplasia...) may be associated with B or C
hepatitis
without any liver symptom. Some of the extrahepatic symptoms observed during chronic hepatitis C therapy with interferon (thyroid dysfunctions, cutaneo-mucous
lichen
) may be related to the immunomodulatory effects of interferon rather than to virus C itself.

The aim of the present study is to carry out a clinical-statistical research into a large number of patients suffering from oral lichen planus (LPO) and from different odontostomatologic pathologies. In both groups of patients serum transaminase values and eventual presence of hepatopathy viral markers were investigated in order to identify a possible correlation between the aforesaid parameters and LPO, considered in its various clinical forms (papular and erosive essentially). Results had showed a close association between hepatopathy and LPO, according to results of studies performed by other Italian and Spanish groups and differently from Anglo-Saxon authors: above all an increased incidence of C
hepatitis
in patients with
lichen
was observed. Furthermore our investigation is agreed in underlining the great importance to attach to erosive form of oral
lichen
, that seems to join to active chronic hepatitis most frequently than papular one.

The article evaluates available scientific information concerning the prevalence and clinical characteristics of hepatitis C virus infection in the Brazilian Amazon, a know endemic area for hepatitis A, B and D viruses infection. All the information was obtained through extensive analysis of original and review articles and abstracts published in distinguished journals or in scientific meetings. In the Amazon Region, HCV infection prevalence rate in the general population varies from 1.1 to 2.4%. Among blood donators the prevalence rate varies from 0.8 to 5.9%. Pard (Eastern Amazon) and Acre (Western Amazon) State present the highest rates, 2% and 5.9%, respectively. In respect to the HCV infection prevalence rate in the risk groups, one observates high prevalence. In the Brazilian Amazon, infection by HCV seems to cope in the same way of infection in other parts of the world among the hemodialized (48.1 - 51.9%), health professionals (3.2%), HCV carriers contactants (10%) and
lichen
plannus patients (7.5%). There is a significant predominance of genotype 1, being sub-type 1b the most frequent. The HCV infection is similar in men and women and most of the infected are above 39 years of age. The major route of infection is parenteral and the major risk factors are blood transfusion and surgical procedures. HCV is rarely responsable for acute severe
hepatitis
in this region. On the other hand, of all chronic hepatitis, 22.6% are attributed to HCV in the Western Amazon and 25% in the Eastern Amazon. In the Brazilian Amazon, infection by HCV seems to cope in the same way of infection in other parts of the world.

Primary cutaneous mucinoses are characterized by abnormal mucin deposits in the skin. Discrete papular
lichen
myxoedematosus (DPLM) is an unusual subtype. Only 11 of the cases described in the literature to date showed no relation to human immunodeficiency virus (HIV) infection. We report a 21-year-old woman with numerous symmetrical asymptomatic papules on her trunk, arms and thighs. Results of investigations were normal. On histological examination, the upper dermis showed a focal mucin deposit. DPLM can be associated with HIV or C
hepatitis
virus (HCV) infection and therefore an early diagnosis is very important.

The association between thymoma and autoimmunity is well known. Besides myasthenia gravis, which is found in 15 to 20% of patients with thymoma, other autoimmune diseases have been reported: erythroblastopenia, systemic lupus erythematosus, inflammatory myopathies, thyroid disorders, Isaac's syndrome or Good's syndrome. More anecdotally, Morvan's syndrome, limbic encephalitis, other autoimmune cytopenias, autoimmune
hepatitis
, and bullous skin diseases (pemphigus,
lichen
) have been reported. Autoimmune diseases occur most often before thymectomy, but they can be discovered at the time of surgery or later. Two situations require the systematic investigation of a thymoma: the occurrence of myasthenia gravis or autoimmune erythroblastopenia. Nevertheless, the late onset of systemic lupus erythematosus or the association of several autoimmune manifestations should lead to look for a thymoma. Neither the characteristics of the patients nor the pathological data can predict the occurrence of an autoimmune disease after thymectomy. Thus, thymectomy usefulness in the course of the autoimmune disease, except myasthenia gravis, has not been demonstrated. This seems to indicate the preponderant role of self-reactive T lymphocytes distributed in the peripheral immune system prior to surgery. Given the high infectious morbidity in patients with thymoma, immunoglobulin replacement therapy should be considered in patients with hypogammaglobulinemia who receive immunosuppressive therapy, even in the absence of prior infection.

The prevalence of psoriasis is 2% of the world's population (1). Inverse psoriasis is characterized by the development of erythematous shiny plaques at intertriginous areas of the body. The prevalence of only anogenital involvement appears to be low, but involvement of the anogenital area together with other areas is found in up to 45% of patients with psoriasis (2). A 21-year-old female student with a 3-month history of mild psoriasis (erythematosquamous plaque on the elbows and nail pitting on the nails of the hand) was referred to our Department. One month earlier, suddenly appearance of erythematous, smooth, clearly demarcated plaques was observed on the labia majora, the mons pubis, the perineal and perianal region together with a brownish hyperkeratotic papule on the pubic region (Figure 1, a-b). The patient underwent excisional biopsy at the Department of Surgery, and the pathohistological finding was unavailable to us. The elbows were treated with corticosteroid-keratolytic preparation, whereas the anogenital lesions were treated with moderately potent topical corticosteroids. In addition to anogenital erythema, on clinical examination we noticed an erythematosquamous plaque on the site of excision with a hyperkeratotic verrucous papule on the edge of the lesion (the Koebner phenomenon on the site of skin injury). In the pubic region, we noticed two hyperkeratotic papules and a few verrucous papules on labia majora. Localized dermatophyte or candida infection were excluded with a KOH test and scrapings culture. Serology for syphilis, HIV, and
hepatitis
were negative. Cervical Pap smear was normal. Biopsy of erythematosus lesion from the mons pubis was conclusive for psoriasis, and of the keratotic papule with the genital wart with positive HPV 6 and 11. The patient's older sister had chronic plaque psoriasis. We employed physically ablative methods like liquid nitrogen cryosurgery, electrocauterization, and curettage, applied topical agents like 0.5% podophyllotoxin solution, 20% podophyllin, and 80% trichloroacetic acid, and treated the psoriatic lesions with a short course of moderate-potency corticosteroids and tacrolimus ointment. All therapeutic attempts were ineffective for curing both diseases. Our patient either had psoriasis with sparse genital warts or exacerbation of multiple anogenital warts (Figure 2, a-b). Anogenital psoriasis is a skin disease that causes great discomfort. The disease-related quality of life is significantly reduced, especially regarding sexual behavior. Therapy for either anogenital psoriasis or genital warts is not entirely satisfactory. Many topical agents suitable for use on the psoriatic lesions on the body, such as coal tar, anthralin, vitamin D derivatives or retinoids, may be too irritating in the anogenital region. The most useful therapy for treatment of anogenital psoriasis are moderately potent topical corticosteroids and topical tacrolimus or pimecrolimus (1). However, corticosteroid-induced atrophy is possible in intertriginous sites. The Koebner phenomenon isomorphic response is the appearance of new skin lesions on areas of cutaneous injury in otherwise healthy skin (3). About 25% of patients with psoriasis have elicitation of psoriatic lesions by injury to the skin (4). Other than in patients with psoriasis, the Koebner phenomenon can be found in other skin diseases like vitiligo, lichen planus,
lichen
nitidus, pityriasis rubra pilaris, flat warts, and keratosis follicularis (Darier disease) (5). According to Eyre at al., about 67% patients with psoriasis (4) present with clearing of psoriatic lesions following skin injury (positive "reverse" Koebner reaction) (4). There is no single treatment for genital warts that is 100% effective, and different types of treatment are very often combined. Accepted methods of treatment involve chemical and physical destruction or removal (6). Since psoriasis koebnerizes, any destructive technique may exacerbate the psoriasis. Coexistence of anogenital psoriasis and HPV presents a huge therapeutic problem because a therapy for psoriasis such as corticosteroids can provoke appearance and/or reappearance of HPV infection, while some therapies for anogenital warts, like cryotherapy, curettage, laser ablation, electrosurgery, or surgery can provoke the appearance and/or reappearance of psoriatic infection due to the Koebner phenomenon.
