Penile ulcerative pyoderma gangrenosum: A rare entity.

Pyoderma gangrenosum (PG) is a rare, chronic, ulcerative, neutrophilic, and inflammatory skin disease. It most commonly affects the lower limb, may affect peristomal skin, and rarely involves mucosal and internal sites. Genital involvement has been rarely reported. Hereby, we report a case of penile PG in a 70-year-old male treated with oral steroids.

An Observational Study of Cutaneous Manifestations in Patients on Chemo and Radiation Therapy for Internal Malignancies at Tertiary Care Center.

Context: Chemotherapy and radiation therapy given to treat internal malignancies may cause cutaneous, hair, nail, and oral mucosal changes. The present study is an effort to know the pattern of cutaneous drug reactions with chemo and radiotherapy. Materials and Methods: Patients of internal malignancies with skin lesions attending the dermatology and oncology OPD/ward were recruited after taking their written consent in vernacular language. A detailed history of skin lesions, malignancies, and treatment was taken. Clinical examination was carried out. Relevant investigations and biopsy were carried out as and when required. Being a descriptive study, age group and gender-wise frequency and percentage were calculated for the treatment of malignancies and dermatosis. Results: The study included 150 patients with 28 different types of internal malignancies, of which 127 (84.66%) patients were treated, 45 (35.43%) treated exclusively with chemotherapy, 16 (12.59%) with exclusive radiation therapy, and 66 (51.96%) with combined chemo and radiation therapy. Total 111 (87.41%) patients received chemotherapy and 82 (64.56%) patients received radiation therapy. Most common internal malignancy was breast carcinoma in 43 (28.67%) cases. Most common chemotherapeutic agent given was paclitaxel to 33 (29.73%) patients. Most common dermatosis associated with exclusive chemotherapy was hand-foot syndrome in 7 (15.55%) cases and with exclusive radiation therapy was radiation dermatitis in 8 (50%) cases. Conclusions: The study was useful in understanding various chemo and radiation therapy-associated dermatosis so that early interventions can be done to prevent further treatment-related adverse effects. Limitation: Small sample size and inability of pinpointing a single drug as the side effect.

An Observational Study of Cutaneous Manifestations in Internal Malignancy at Tertiary Care Centre.

Introduction: Skin is the largest organ in the human body and mirrors the changes in the organism it envelops. Internal malignancies can cause various specific and non-specific cutaneous manifestations along with hair, nail and oral mucosal changes. Some of the changes are detected early indicating a strong association with cancer, while some occur in later stage indicating dissemination or immunosuppression. The present study is an effort to know pattern of dermatosis associated with internal malignancies so that early diagnosis and interventions can be done. Aim: To determine the pattern of specific and non-specific dermatosis associated with internal malignancy. Methods and Material: Patients of internal malignancies with skin lesions attending dermatology and oncology department during July 2020 to June 2021 were recruited in the study after taking written informed consent. A detailed history of skin lesions and malignancies were taken. Clinical examination (skin/hair/nail) was carried out and photographs were taken. Relevant investigations were carried out. Frequency and percentage of dermographic data and dermatosis associated with internal malignancies were calculated. Results: The study included 150 patients with maximum number of patients 78 (52%) in 41-60 years of age group with female: male ratio of 1.2:1. Most common internal malignancy was breast carcinoma in 43 (28.67%) cases. Specific dermatosis were seen in 5 (3.33%) cases and non-specific dermatosis in 121 (80.66%) cases. Specific dermatosis were vasculitis, necrolytic migratory erythema, lymphocytoma cutis, growth and cutaneous metastasis with 1 (0.67%) patient each. Most common non-specific dermatosis was herpes zoster in 17 (11.33%) cases. Conclusion: The study was useful in understanding the various specific and non specific dermatosis associated with internal malignancies and thereby helping the physician to manage the conditions.

Plica Neuropathica: Bird's Nest under Dermatoscope.

Plica polonica is a rare condition presenting as a mass of scalp hair with irregular twists and irreversibly entangled plaits, which are firm to hard impenetrable mass of keratin cemented together with dirt and exudates. The exact etiopathogenesis of plica neuropathica is not known, but it can be due to longitudinal splitting or weathering of hair shaft due to vigorous friction and frequent use of harsh shampoos and cleansers or long hair with poor hair care Drug-induced hair matting due to chemotherapeutic drugs and due to neurotic illness like hysteria, anxiety, to psychotic illness have also been reported. Dermatoscopy showed interwining of hair shaft with matting and honey-colored concretions mimicking "wrangled mesh of wires" appearance. The treatment of plica neuropathica involves cutting the matted hair and evaluating underlying psychiatric illness to prevent recurrence.

Atypical Presentation of Halo Nevus over Eyelid with Poliosis: A Dermatoscopic Perspective.

Halo nevus (HN) is benign skin condition with a central melanocytic nevus, surrounded by an area or halo of depigmentation. It is the result of immunological response of the body toward the nevus, which destroys the melanocytes in surrounding skin, leading to the depigmented halo. An increased frequency of HN in patients with vitiligo is observed. It is more commonly seen in children or young adults of either sex, particularly on the trunk, less commonly on the face, neck, and limbs. We present a rare case of HN which was present on the lower eyelid associated with poliosis, diagnosed with dermatoscopy.

Topical steroids: Awareness and misuse among patients, pharmacists and general medical practitioner.

AIMS AND OBJECTIVES: (1) To determine the level of awareness among patients, pharmacists and general practitioners about commonly available topical steroids and its combinations.(2) To determine the source of recommendation/prescription of topical steroids and its combination creams.(3) To know and create awareness about the side effects of topical steroids in all the study groups. METHODS: This was a prospective questionnaire-based study where three study groups, namely patients, pharmacists and general practitioners, were included. This study was approved by the institutional ethics committee. after ethical clearance. The patients who used topical steroids for dermatoses where it is an absolute contraindication, as well as those who developed side effects, were included in the study. ThoroughComplete cutaneous examination was done specifically to detect the side effects of steroids. Seminars were conducted and questionnaires were given to both the pharmacists and general practitioners of nearby areas. The questionnaire consisted of questions regarding their prescription and dispensing practices of topical steroids and its combinations. RESULTS: Out of 95 patients seen, the most commonly used steroid molecule was clobetasol propionate 0.05% in 44 (46.3%) patients, the common source of recommendation was general practitioners in 36 (37.8%), the common indication was superficial dermatophytosis in 85 (89%) and the most common adverse effect was recurrence/increase in the extent of the infection in 72 (75.78%) patients. Out of total 44 general practitioners enrolled in the study, 22 (50%) were qualified allopathic medical practitioners and22 (50%) were homeopathic/ayurvedic doctors. Superficial dermatophytosis [19 (43.18%)] was the common dermatosis seen by them. While 29 (65.90%) preferred prescribing topical steroids or its combination, rest of them preferred plain steroid creams. Out of 179 pharmacists, 74 (41.34%) did not have appropriate knowledge of topical steroids, 35 (19.55%) were not aware that steroids are isschedule "H" drugs. Commonest molecule sold over the counterwas clobetasol propionate 0.05% by 74 (41.89%). The limitations of our study were small study group and short duration. CONCLUSION: As dermatologists, it is our responsibility, to correctly educate the society, particularly the non-dermatologist medical fraternity, about ethical and rational use of topical steroids.

Dermoscopy in general dermatology (non-neoplastic dermatoses) of skin of colour: a comparative retrospective study by the International Dermoscopy Society.

BACKGROUND: Dermoscopy has been shown to be a useful supportive tool to assist the diagnosis of several non-neoplastic dermatoses (i.e. inflammatory, infiltrative and infectious skin diseases), yet data on skin of colour is still limited. OBJECTIVES: To characterize dermoscopic features of non-neoplastic dermatoses in dark-skinned patients in order to identify possible clues that may facilitate the differential diagnosis of clinically similar conditions. MATERIALS & METHODS: Members of the International Dermoscopy Society were invited to submit cases of any non-neoplastic dermatosis developing in patients with Fitzpatrick Phototypes V-VI whose diagnosis had been confirmed by the corresponding gold standard diagnostic test. A standardized assessment of the dermoscopic images and a comparative analysis according to clinical presentation were performed. Seven clinical categories were identified: (I) papulosquamous dermatoses; (II) facial hyperpigmented dermatoses; (III) extra-facial hyperpigmented dermatoses; (IV) hypopigmented dermatoses; (V) granulomatous dermatoses; (VI) sclerotic dermatoses; and (VII) facial inflammatory dermatoses. RESULTS: A total of 653 patients (541 and 112 with Phototype V and VI, respectively) were recruited for the analysis. Thirty-six statistically significant dermoscopic features were identified for papulosquamous dermatoses, 24 for facial hyperpigmented disorders, 12 for extra-facial hyperpigmented disorders, 17 for hypopigmented disorders, eight for granulomatous dermatoses, four for sclerotic dermatoses and 17 for facial inflammatory diseases. CONCLUSION: Our findings suggest that dermoscopy might be a useful tool in assisting the diagnosis of clinically similar non-neoplastic dermatoses in dark phototypes by revealing characteristic clues. Study limitations include the retrospective design, the lack of a direct dermoscopic-histological correlation analysis and the small sample size for less common diseases.
