Angiolymphoid hyperplasia with eosinophilia (ALHE) is an idiopathic acquired condition characterized by erythematous papulo-nodular lesions with a predilection for the head and neck. The lesions are cosmetically disfiguring, resistant to most medical and surgical therapies and tend to recur. We report the novel use of radiofrequency equipment in the management of nodular ALHE on forehead of a 53-year-old man. Intra-lesional radiofrequency ablation was done using a modified 18 gauge intravenous cannula and three sittings over a period of four years yielded cosmetically acceptable results with no recurrence and minimal side effects.

Use of rituximab in patients with chronic viral hepatitis can worsen pre-existing hepatitis or reactivate occult infection. There are no reports of use of rituximab in pemphigus patients with co-existing viral hepatitis. Herein, we report three pemphigus patients with co-existing chronic viral hepatitis (hepatitis C (n = 2), hepatitis B (n = 1)), who were treated successfully with rituximab under close supervision and concurrent antiviral drug administration. There was no derangement of the liver function tests or increase in viral load in any of the patients. By incorporating good collaboration with a hepatologist and close follow-up, such patients can be managed successfully with biologic therapies when the conventional treatment modalities have failed.

A 55-year-old woman on treatment with capecitabine and paclitaxel for breast carcinoma presented with history of a tingling sensation in her hands and feet with a progressive burning sensation. She also noted discomfort, minimal pain and stiffness while holding objects. On examination, there was patchy hyperpigmentation of both the palms and soles, and the dorsa of hands and feet. This was accompanied by a thickening of the skin more over the knuckles and toes. In addition there was a moist desquamation around the toes and over the palmar creases and a bluish discoloration of the lunulae of both thumbnails. She was diagnosed with hand and foot syndrome and started on pyridoxine and emollients. The finding of keratoderma noted in our patient is not seen commonly in hand and foot syndrome.

Background: The color of Indian skin shows great diversity and pigmentary disorders are a major concern of Indian women. Despite great variations in climate, diet, and social parameters within India, studies of the range of skin types have been rather scarce. Aims: This study was aimed at characterizing the color of Indian skin in various geographical locations, its characteristics in terms of overall skin complexion and pigmentary disorders, and the impact of age on these features. Methods: An extensive descriptive study, including skin color parameters (objective measurements and evaluations by dermatologists, clinically or from photographs) was carried out involving 1,204 female volunteers of different ages living in four different Indian cities. Results: Important differences in skin complexion according to the geographical location were observed. Age seemed to have little impact on complexion. Hyperpigmented spots were frequent and were noted at early stages and many lentigines were found. Melasma affected about 30% of middle-aged women, but many other ill defined, pigmented macules were also observed. Additionally, we found pigmented lip corners associated with marionette lines, and linear nasal pigmentation. Conclusions: Indian skin color is diverse and pigmentary disorders are common. Skin complexion is not greatly affected by age. Some hyperpigmented disorders occur at early stages and increase with age, contributing to overall unevenness of facial color.

Background: Leprosy remains an important health problem mainly in the African and South-East Asia regions. Type 1 reaction is an immune-mediated phenomenon known to complicate at least 30% of patients of leprosy. Diagnosing type 1 reaction correctly is important for timely institution of therapy to prevent and treat neuropathy-associated disability and morbidity. There is paucity of literature on definitive criteria for histologic diagnosis of type 1 reaction. This study was conducted to determine the key histologic variables for diagnosing type 1 reaction. Methods: This was a prospective study recruiting 104 patients with borderline leprosy. Three pathologists blinded to the clinical diagnosis independently assessed the cases. The agreement between each histological variable and clinical diagnosis was then calculated by using Cohen's kappa (Κ) coefficient. Results: Histological diagnosis of type 1 reaction was given to 27 (67.5%) of 40 clinically diagnosed cases of type 1reaction cases. Histological variables chosen as key variables for histological diagnosis of type 1 reaction were presence of giant cells, dermal edema, intragranuloma edema, granuloma fraction 31-50%, and presence of medium to large giant cells. Conclusion: This study has shown that T1R are still underdiagnosed histologically in comparison with clinical assessments. The key variables for diagnosing type 1 reaction were proposed.

Background: Striae distensae or stretch marks are atrophic linear dermal scars with epidermal atrophy. There are many therapeutic options for management, but no consistently effective modality is available yet. Objective: We compared the efficacy of 1064 nm long pulse (LP) Nd: YAG laser and 2940 nm variable square pulse (VSP) erbium: YAG laser in the treatment of striae distensae. Methods: Twenty female volunteers (Fitzpatrick skin types II-V) aged between 20 and 40 years with striae (3 patients with the rubra type and 17 with the alba type) were enrolled in the study. The duration of striae ranged from 4 months to 12 years. Lesions were located on the abdomen in all patients except one patient who had striae on the arms and two patients with striae in the lumbar region. Treatments were randomly allocated to both sides of the body in each patient, one side being treated with VSP erbium: YAG laser and the opposite side with LP Nd: YAG laser. All subjects were treated monthly for a total of three treatments. Two 3-mm punch biopsies were obtained from six subjects, both of the same striae, one before the first treatment and one 4 weeks after the last session. Results: Response was evaluated clinically by photographic comparison and was found to be poor in 17 subjects, both on the LP Nd: YAG laser treated side and VSP erbium YAG laser treated side. All these patients had mature lesions (striae distensae alba). Three subjects had a moderate response on both sides; these patients' striae were immature (striae distensae rubra). Histologically, elastic fibers were slightly increased in post-treatment samples compared with pretreatment skin biopsies. Conclusion: We observed no satisfactory clinical improvement in striae distensae alba lesions although histopathological changes were seen. We suggest that variable square pulse Er: YAG and long pulse Nd: YAG lasers are not useful in the treatment of striae distensae alba.

Background: Leukoplakia is the most common premalignant lesion of the oral mucosa. We studied the colonization of Candida in oral leukoplakia using direct microscopy, culture and histopathology to determine if there is a statistical correlation between Candida invasion and the clinical appearance and presence of epithelial dysplasia in leukoplakia. Methods: Samples were collected from 40 patients with oral leukoplakia and 21 controls. The swabs collected were used to inoculate Sabouraud's dextrose agar slant and for direct microscopy with Gram's stain. Culture growths were subjected to germ tube and corn meal agar tests to differentiate between Candida albicans and non-albicans groups. Biopsies were also done in all patients for histopathological confirmation; Gomori's methanamine silver stain was used to identify fungal invasion of lesional epithelium. Results and Conclusions: Nineteen cases of leukoplakia showed Candida on direct smears, compared to 3 controls. Eighteen cases and one control showed growth of Candida on culture. Non-homogenous leukoplakia showed a higher positivity rate on microscopy and culture than homogenous lesions. All these correlations were statistically significant. Forty percent of leukoplakia cases were simultaneously positive for Candida on direct microscopy, culture and histopathologic evaluation. No significant difference was found between non-dysplastic and distinctly dysplastic lesions with respect to Candida detection on microscopy or culture.
