Rapamycin (sirolimus) is a fungal fermentation product that inhibits the proper functioning of a serine/threonine protein kinase in mammalian cells eponymously named mammalian target of rapamycin, or mTOR. Rapamycin is a novel class of anticancer and immunosuppressant drugs targeting the proteins at molecular level. Rapamycin (sirolimus) is routinely incorporated in drug-eluting stents used for cardiac angioplasty. In recent years, rapamycin was found to be efficacious in managing the symptom complex of tuberous sclerosis, i.e. renal angiomyolipoma, giant cell astrocytoma and pulmonary lymphangiomyomatosis. Various investigators have also proved that topically applied rapamycin causes regression of facial angiofibromas, giving better cosmetic results.

Acne inversa (AI) is a disabilitating chronic inflammatory disease with major negative impact on quality of life and significant co-morbidities. This is an important link to insights into immune dysfunction, which stimulated therapeutic approaches like tumor necrosis-α inhibitor therapy. This new off-label drug treatment is particularly beneficial when used in combination with wide excision of inflamed skin and subcutaneous tissue. Retinoids have been reported to be helpful in secondary prevention. The standard of therapy in advanced cases is surgery with wide excisions and healing by secondary intention. This treatment results in significant reduction of complaints and achieves satisfactory body contouring.

Basal cell carcinoma (BCC) is the most common paraneoplastic disease among human neoplasms. The tumor affects mainly photoexposed areas, most often in the head and seldom appears on genitalia and perigenital region. BCC progresses slowly and metastases are found in less than 0.5% of the cases; however, a considerable local destruction and mutilation could be observed when treatment is neglected or inadequate. Different variants as nodular, cystic, micronodular, superficial, pigment BCC are described in literature and the differential diagnosis in some cases could be difficult. The staging of BCC is made according to Tumor, Node, Metastasis (TNM) classification and is essential for performing the adequate treatment. Numerous therapeutic methods established for treatment of BCC, having their advantages or disadvantages, do not absolutely dissolve the risk of relapses. The early diagnostics based on the good knowledge and timely organized and adequate treatment is a precondition for better prognosis. Despite the slow progress and numerous therapeutic methods, the basal cell carcinoma should not be underestimated.

Background: Tinea capitis is a superficial fungal infection of the hair follicle of scalp. Most of the dermatophytosis do not have such age propensity as tinea capitis which almost invariably involves the paediatric age group. The exact incidence of tinea capitis is not known. This study is done in order to isolate the species variation in an area, to know the changing patterns of occurrence of different species and their association with clinical pattern Materials and Methods: All clinically diagnosed cases of tinea capitis which presented to our out patient department over a period of one year were included in the study. Results: 70 cases of Tinea capitis were studied. Discussion: Tinea capitis is a disease of prepubertal children with common in age group of 5- 15 years. The incidence varies from 0.5% to 10%. Most common presenting feature was alopecia.

Lethal midline granuloma is a relatively rare disease characterized by destruction and mutilation of the nose and other structures of respiratory passages. The nonspecificity of symptoms obscures the correct diagnosis and is responsible for the delay in treatment which can be detrimental as this grave disease calls for urgent intervention. We present a case report of this disease in a 35 year old male who gave a short two month history of the clinical symptoms.

Background: Chronic renal failure (CRF) is associated with a variety of cutaneous manifestations as a result of underlying etiology as well as the various treatment modalities. Aim: To evaluate the prevalence of various dermatoses in patients with CRF on hemodialysis and to study the effect of hemodialysis on the intensity of pruritus. Materials and Methods: A total of 35 patients of CRF on hemodialysis having at least one cutaneous manifestation were included in the study. Results: Twenty-four (68.71%) cases in our study belonged to the age group of 50-69 years, out of which 16 cases were in the sixth decade. Xerosis and pruritus occurred in 80% and 65.71% of cases, respectively. Other common findings included pallor (68.57%), dyspigmentation (34.29%), cutaneous infections (34.39%), acquired perforating dermatosis (17.4%), and nail changes (60%). Hemodialysis failed to improve pruritus in 17 (73.9%) of our patients. Twenty-six patients (74.28%) suffered from hypertension, 13 of them also were known cases of type II diabetes mellitus. Five patients suffered exclusively from type II diabetes mellitus. Conclusions: In our small study, xerosis was the commonest finding and pruritus, the commonest symptom. The intensity of pruritus was largely unaffected by hemodialysis.

Granuloma faciale (GF) is an uncommon, cutaneous disorder characterized by one to several soft, erythematous to livid papules, plaques, or nodules, usually occurring on the face. Extra-facial lesions occur rarely. We present a case report of 33-year-old male who presented with keloidal lesions on face and left shoulder. The patient didn't respond with intralesional triamcinolone and showed poor response with the addition of topical tacrolimus. Surgical excision in consultation with plastic surgeons is planned.

Ashy dermatosis is a disorder of pigmentation, characterized by asymptomatic symmetric ashy gray-colored macules, in the first to third decade of life. It can, however, affect children sometime. But, there is a paucity of similar cases in Indian children. We present a case of ashy dermatosis in an 8-year-old Indian girl who presented to skin OPD with areas of ashy pigmentation, which were distributed symmetrically. Skin biopsy was consistent with lichenoid pattern histology. This case has been reported to highlight the rarity of ashy dermatosis in Indian children.

Pyoderma gangrenosum is a rare noninfective neutrophilic dermatosis, characterized by progressive painful ulceration. It is frequently associated with systemic disorders like inflammatory bowel disease, rheumatoid arthritis and myeloproliferative diseases. However, its association with infectious diseases in particular with tuberculosis is extremely rare. Diagnosis is based on the history of an underlying disease, a typical clinical presentation, histopathology and exclusion of other diseases leading to ulcerations of similar appearance. Immunosuppression with corticosteroids remains the mainstay of treatment. We report a case of a 49-year-old male with long-standing ulcerative colitis, associated with tuberculosis of hip, who presented with nonhealing ulcers over the lower extremity.

Central centrifugal cicatricial alopecia is a common cause of progressive permanent apical alopecia. This unique form of alopecia includes entities previously know as "hot comb alopecia," "follicular degeneration syndrome," "pseudopelade" in African Americans and "central elliptical pseudopelade" in Caucasians. The etiology appears to be multifactorial and the condition occurs in all races.

Granular cell tumor (GCT) is an uncommon tumor and is believed to be of schwannian origin. GCT is benign but rare malignant cases are recorded. GCT occurs in almost any part of the body. The common sites are the tongue, skin, and subcutaneous tissue. GCT of hand is an extremely rare. Till date only 17 cases are reported in the literature. Preoperative diagnosis of GCT is important, because GCT mimics dermal adnexal tumor in subcutaneous tissue, other soft tissue tumor or inflammatory lesions. GCT is composed of large polygonal cells with eosinophilic granular cytoplasm and these cells are often immunoreactive for the S-100 protein. Fine-needle aspiration cytology has been suggested to be diagnostic modality of choice and this would undoubtedly aid the correct diagnosis. Excision with wide surgical margins is curative for benign GCT. Recurrence and malignant transformation requires regular follow-up. Here, this communication documents a case of cytological diagnosis of the granular cell tumor of hand in a 21-year-old female, clinically suspected to be a dermal adnexal tumor.
