Solitary eccrine syringofibroadenoma with nail involvement: A rare entity.

Eccrine syringofibroadenoma (ESFA) is a rare, benign tumor of eccrine sweat gland origin that usually presents as a nodule on the extremities of an elderly person. It can also present as an ulcerative plaque, verrucous lesion, papular or nodular lesion or as palmoplantar keratoderma. Although the clinical features are variable, histology is characteristic in the form of anastomosing strands, cords and columns of epithelial cells embedded in a fibrovascular stroma. We report the case of a 62-year-old male with a nodular lesion on the extremity that caused secondary involvement of the nail in the form of complete nail dystrophy. The histology showed features consistent with ESFA. Nail involvement by ESFA is a rare presentation and is rarely described in the literature.

Acquired Port-wine Stain in an Adult Male: First Reported Case from India with Review of Literature.

Port-wine stains (PWSs) are congenital vascular lesions caused by progressive ectasia of blood vessels located in the vascular plexus of the dermis. Acquired PWSs develop later in life but are identical in morphology and histology to the congenital PWSs. Less than 75 cases of acquired PWSs have been reported in the published literature, of which there has not been a single report from India so far. Various factors have been proposed for its pathogenesis like trauma, actinic exposure, drugs, tumors, and herpes zoster infection. We report an acquired port-wine stain in a 41-year-old male. The causative factors, treatment, and previous reports of this uncommon entity have also been reviewed.

A clinicotherapeutic analysis of Stevens-Johnson syndrome and toxic epidermal necrolysis with an emphasis on the predictive value and accuracy of SCORe of Toxic Epidermal Necrolysis.

BACKGROUND: The SCORTEN scale (SCORe of Toxic Epidermal Necrolysis) is widely used to predict mortality in patients with Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). Although it is largely a useful tool, the predictive ability of the scale is variable, and modifications to the existing scale have been suggested. In addition, there is controversy regarding the roles of active therapy and conservative management. OBJECTIVES: This study was conducted to assess outcomes in SJS/TEN patients managed conservatively and to analyze the predictive performance of SCORTEN. METHODS: Sixty patients were studied prospectively from October 2008 to September 2011. The accuracy of SCORTEN in predicting mortality was analyzed on days 1, 3, and 5 of admission. All patients were managed conservatively. RESULTS: The discriminative power of SCORTEN was acceptable, being best on day 5. The agreement between actual and predicted mortality was poor, as indicated by a low P-value of the Hosmer-Lemeshow statistic. Only three parameters (heart rate, blood urea, and serum bicarbonate) were found to be significant on multivariate analysis, and all of these represented components within the original SCORTEN scale. The mortality rate was 16.7%. All deaths occurred within the first two weeks (8-12 days). CONCLUSIONS: Serial analysis using SCORTEN is better than analysis performed only on day 1. Although the scale is largely useful, its performance is influenced by the demographic profile of the study population; minor modifications based on the population studied may increase the predictive accuracy of the original SCORTEN. In addition, conservative management is a valid therapeutic option, is preferable to treatment with steroids and immunosuppressants, and is highly recommended.

Palatal ulceration.

Palatal ulcers are a common presentation and can be conveniently divided into developmental and acquired causes, the latter of which is subdivided into acute and chronic causes. Most commonly seen dermatologic causes have associated skin manifestations. Acute and multiple ulcers are usually infectious or drug induced in origin. Recurrent ulcers are largely dominated by aphthosis, while chronic ulcers are seen in immunocompromised patients and can occasionally be malignant. It is essential to involve the oral and maxillofacial surgeons early in the therapeutic management to tackle the inevitable complications that may ensue in the chronic cases.

Concurrent hand-foot skin reaction and hair depigmentation with sunitinib: report of a case and literature review of kinase inhibitors and blocking antibodies.

Kinase inhibitors have revolutionized cancer therapy by becoming the first-line agents for advanced solid malignancies replacing the traditional chemotherapeutic agents. Cutaneous side-effects with these drugs are common, but owing to their infrequent use in Indian patients, our current knowledge of toxicity is scanty and primarily based on the western literature. Cutaneous reactions can adversely affect patients' quality of life (QoL) and can lead to dose modifications and treatment interruptions. The report discusses concurrent hand-foot skin reaction (HFSR) and hair depigmentation in an Indian patient being treated with sunitinib for advanced renal cell carcinoma. The pathogenesis and treatment strategies for this characteristic phenomenon and other cutaneous toxicities of kinase inhibitors have also been reviewed.

A rare presentation of mammary Paget's disease involving the entire breast in the absence of any underlying ductal malignancy.

Paget's disease of the breast is an uncommon form of breast cancer presenting as an eczematous eruption over the nipple and/or areola. The diagnosis remains elusive with varied presentations, mimicking many benign skin diseases, the awareness of which is indispensable for diagnosis and minimizing morbidity. Most of the cases have an associated malignancy of the underlying breast tissue. There have been very few reports wherein the disease has occurred independent of any underlying malignancy. Since, the initial presentation is limited to skin; it is the dermatologist who plays a key role in making a diagnosis, thus, facilitating proper management. We report a rare presentation of mammary Paget's disease with a wide cutaneous spread probably attributed to a significantly delayed diagnosis without any associated underlying malignancy.

Chemical peels for melasma in dark-skinned patients.

Melasma is a common disorder of hyperpigmentation, which has a severe impact on the quality of life. Inspite of tremendous research, the treatment remains frustrating both to the patient and the treating physician. Dark skin types (Fitzpatrick types IV to VI) are especially difficult to treat owing to the increased risk of post-inflammatory hyperpigmentation (PIH). The treatment ranges from a variety of easily applied topical therapies to agents like lasers and chemical peels. Peels are a well-known modality of treatment for melasma, having shown promising results in many clinical trials. However, in darker races, the choice of the peeling agent becomes relatively limited; so, there is the need for priming agents and additional maintenance peels. Although a number of new agents have come up, there is little published evidence supporting their use in day-to -day practice. The traditional glycolic peels prove to be the best both in terms of safety as well as efficacy. Lactic acid peels being relatively inexpensive and having shown equally good results in a few studies, definitely need further experimentation. We also recommend the use of a new peeling agent, the easy phytic solution, which does not require neutralisation unlike the traditional alpha-hydroxy peels. The choice of peeling agent, the peel concentration as well as the frequency and duration of peels are all important to achieve optimum results.

Epidermolysis bullosa: where do we stand?

Epidermolysis bullosa, a genetically determined skin fragility disorder can severely incapacitate the life of the afflicted patient. Although the clinical features are multiple and varied, treatment still remains a major challenge. There have been major changes in the classification of the disease recently. Although there is still a long way to go, good nursing care, and gene therapy could possibly significantly alleviate the suffering of the patients in the future.
