Rosai-Dorfman syndrome is characterized by sinus histiocytosis with massive lymphadenopathy. A 25-year-old woman presented with multiple erythematous and yellowish papules on the forehead, cheeks, chin and thigh. She had massive generalized, firm, non-tender and non-matted lymphadenopathy and mild hepatomegaly. Her hemogram was normal. A skin biopsy showed collections of histiocytes with emperipolesis and plenty of plasma cells. A lymph node biopsy showed partial loss of architecture, dilated sinuses filled with histiocytes, which showed lymphocytophagocytosis, anisonucleosis and a clear cytoplasm. She was referred to an oncologist for further management.

A 17-year-old boy had a 3-year history of diabetes mellitus, malabsorption syndrome, and skin changes consisting of induration, hyperpigmentation, and hypertrichosis on the anterior aspect of both thighs, lower abdomen, and scrotum. Physical examination found hypogonadism, hepatomegaly, gynecomastia, growth retardation, and ankle edema. There was no neuropathy or plasma cell dyscrasia. However, the characteristic skin changes and the combination of symptoms suggest polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes syndrome. This is a rare multisystemic disorder of obscure pathogenesis and no conspicuous heredity. Overproduction of vascular endothelial growth factor is thought to cause microangiopathy, neovascularization, and accelerated vasopermeability causing the multiorgan deterioration. Cyclophosphamid cytostatic therapy seems beneficial.

Argininosuccinicaciduria is a rare metabolic disorder of the urea cycle associated with the inability to excrete nitrogenous waste in the form of urea. Along with low serum arginine, hepatomegaly, and mental retardation, congenital trichorrhexis nodosa is a distinguishing feature of the disorder. We present a 3.5-year-old girl diagnosed with argininosuccinicaciduria who presented to the dermatology clinic with hair thinning and loss since birth. Microscopic evaluation revealed nodular swellings on the hair shafts and frayed cortical fibers consistent with the diagnosis of trichorrhexis nodosa occurring in the setting of argininosuccinicaciduria.

A four-year-old girl was brought to the dermatology outpatient department with scaling all over the body since birth. She had history of episodic vomiting and abdominal distension. A dermatological diagnosis of lamellar ichthyosis was made. Abdominal examination revealed a nontender hepatomegaly, fatty liver on ultrasonography and deranged liver function tests. Peripheral blood smear showed lipid vacuoles in the granulocytes consistent with Jordans' anomaly. Similar lipid vacuoles were seen in the basal layer in skin biopsy. An inflammatory infiltrate, moderate fibrosis in the portal tract and diffuse severe fatty change in hepatocytes were seen in liver biopsy. The patient was diagnosed as a case of Dorfman-Chanarin syndrome.

A novel pigmented dermatosis was observed in four unrelated boys, three of whom had insulin-dependent diabetes. Three patients were the offspring of consanguineous parents. All four boys had pigmented hypertrichotic patches or induration on the upper inner thighs, with variable involvement of the genitalia, trunk, and limbs. Two boys had episcleritis and orbital proptosis with similar facies and musculoskeletal abnormalities including clinodactyly, flat feet, and short stature. One child had paraaortic and inguinal lymphadenopathy and three patients had an enlarged liver and spleen. A large, swollen pancreas was observed on ultrasound imaging in one patient with insulin dependent diabetes who also had echocardiographic evidence of pericardial inflammation. Three boys had elevated laboratory markers of inflammation. Biopsy specimens from the skin and orbit showed a chronic inflammatory cell infiltrate composed of polyclonal lymphocytes, histiocytes, and plasma cells; fibrosis was observed in two patients, one of whom had previously received radiation therapy to the orbit. Two boys responded to treatment with subcutaneous interferon-alpha, combined with a short course of oral prednisone in the child without diabetes. We believe these inflammatory pigmented skin lesions represent a unique dermatosis associated with diabetes mellitus and systemic disease. The pathogenesis is unknown. The presence of consanguinity in three of four families, and similar dysmorphic features in two boys, suggest a genetic disorder, possibly with autosomal recessive inheritance.

Dorfman-Chanarin syndrome is a rare, autosomal recessive inherited lipid storage disease with congenital ichthyotic erythroderma due to an acylglycerol recycling defect. It is characterized by accumulation of neutral lipids in different tissues. Liver, muscle, ear, eye, and central nervous system are generally involved, so we presented a patient with severe ichthyosis, lipid vacuoles in neutrophils, and multiorgan involvement including a very rare complication, renal involvement. A 7-month-old girl was presented with frequent respiratory infection, congenital ichthyotic erithroderma and suspicion for immune deficiency. On her physical examination hepatomegaly, developmental delay, palmar and plantar hyperkeratosis and increased deep tendon reflexes with clonus and high tonus were found. Laboratory investigations revealed elevation at transaminases levels, hypoalbuminemia, hypergammaglobulinemia, presence of autoantibodies and eosinophilia. Vacuolization in leukocytes confirmed Dorfman-Chanarin syndrome, whereas no mutation at RAG1-2 and ARTEMIS genes ruled-out immune deficient status of the patient. At the age of eight months the patient died from severe renal failure. Her necropsies demonstrated microvesicular lipid accumulation not only at the liver but also at the renal species. The variability of involvement of different systems in Dorfman-Chanarin syndrome is well described, however the renal findings has not been reported previously at the literature.

Arsenicosis is a multisystem disorder, with virtually no system spared from its vicious claw; though its predominant manifestations are linked to cutaneous involvement. Cutaneous effects take the form of pigmentary changes, hyperkeratosis, and skin cancers (Bowen's disease, squamous cell carcinoma, and basal cell epithelioma). Peripheral vascular disease (blackfoot disease), hypertension, ischemic heart disease, noncirrhotic portal hypertension, hepatomegaly, peripheral neuropathy, respiratory and renal involvement, bad obstetrical outcome, hematological disturbances, and diabetes mellitus are among the other clinical features linked to arsenic toxicity. The effects are mediated principally by the trivalent form of arsenic (arsenite), which by its ability to bind with sulfhydryl groups present in various essential compounds leads to inactivation and derangement of body function. Though the toxicities are mostly linked to the trivalent state, arsenic is consumed mainly in its pentavalent form (arsenate), and reduction of arsenate to arsenite is mediated through glutathione. Body attempts to detoxify the agent via repeated oxidative methylation and reduction reaction, leading to the generation of methylated metabolites, which are excreted in the urine. Understandably the detoxification/bio-inactivation process is not a complete defense against the vicious metalloid, and it can cause chromosomal aberration, impairment of DNA repair process, alteration in the activity of tumor suppressor gene, etc., leading to genotoxicity and carcinogenicity. Arsenic causes apoptosis via free radical generation, and the cutaneous toxicity is linked to its effect on various cytokines (e.g., IL-8, TGF-beta, TNF-alpha, GM-CSF), growth factors, and transcription factors. Increased expression of cytokeratins, keratin-16 (marker for hyperproliferation) and keratin-8 and -18 (marker for less differentiated epithelial cells), can be related to the histopathological findings of hyperkeratosis and dysplastic cells in the arsenicosis skin lesion.

Several syndromes manifest as recurrent daily fevers, skin lesions, and multisystem inflammation. We describe 4 patients with early-onset recurrent fevers, annular violaceous plaques, persistent violaceous eyelid swelling, low weight and height, lipodystrophy, hepatomegaly, and a range of visceral inflammatory manifestations. Laboratory abnormalities included chronic anemia, elevated acute-phase reactants, and raised liver enzymes. Histopathologic examination of lesional skin showed atypical mononuclear infiltrates of myeloid lineage and mature neutrophils. Our patients have a distinctive early-onset, chronic inflammatory condition with atypical or immature myeloid infiltrates in the skin. We propose the acronym CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature) syndrome for this newly described disorder, which is probably genetic in origin.

A 4-year-old, ovariohysterectomized, English springer spaniel on immunosuppressive therapy was re-examined for the review of its immune-mediated haemolytic anaemia and the recent development of skin lesions. For the 3 months since hospital discharge, the dog had been receiving 1.3 mg/kg prednisolone and 2.6 mg/kg ciclosporin, both administered orally twice daily. Physical examination revealed hepatomegaly and multiple, purulent, crusting, erosive to ulcerative lesions over different body areas. Onychorrhexis had occurred on one digit and the underlying corium had blackened. There were two proliferative and one plaque-like lesions in the mouth. Thick walled fungal hyphae were detected in impression smears from all skin lesions and staining with periodic acid-Schiff's stain confirmed the presence of multiple fungal hyphae and spores in all biopsies examined. Fungal culture isolated a heavy, pure growth of an Alternaria sp. which was identified as A. infectoria by sequencing the internal transcribed spacer 1 region of the rRNA gene. The animal's condition prevented detailed investigation of the oral lesions. Withdrawal of the ciclosporin and reduction of the prednisolone dosage resulted in spontaneous resolution of the skin lesions within 40 days. Further gradual decrements in the prednisolone dosage to zero were carried out without recurrence of the immune-mediated haemolytic anaemia. After 12 months, there has been no recurrence of either the skin lesions or the anaemia. To the authors' knowledge, this is the first reported case of A. infectoria infection in a dog.

A 50-year old woman was admitted with pre-Se'zary syndrome in May, 97 as she had intractable progressive erythroderma with intense pruritus since 15 months. She also had axillary, inguinal, hilar and para-aortic lymphadenopathy, hepatomegaly, alopecia, hypersensitivity to cefadroxyl, and abnormal Sezary cells in peripheral blood film. Histopathology confirmed the diagnosis. Initially she was given 20 mg of prednisolone which was later increased to 40 mg daily but she did not respond. She responded favourably to combination of 20 mg prednisolone and chlorambucil 2.5 mg daily.
