Sexual problems that are psychological in origin, rather than physiological, are called psychosexual disorders. Multiple factors, such as general health of the patient, chronic illnesses, psychiatric/psychological disorders, and socio-cultural factors, alone or in combination can be attributed to the development of psychosexual dysfunctions. The symptoms of these disorders vary for each individual and differ with gender. These disorders may be categorized as sexual dysfunction, paraphilias, and gender identity disorders. Dermatologists are sometimes consulted for sexual dysfunctions in their routine practice by the patients visiting sexually transmitted infections (STI) clinics because a majority of the patients believe that these problems are caused by dysfunctions in the sex organs, and because people are hesitant to go to sexuality clinics and psychiatrists for such problems. Sometimes these patients are referred from other specialties such as urology or gynecology; most often, we attempt to search for STIs or other dermatoses on the genitalia and refer them back. We often underestimate the prevalence of sexual concerns of the patients or feel uncomfortable discussing matters of sexuality with them. Dermatologists should understand basic sexual medicine and ask patients for sexual problems. They should be trained to manage such patients accordingly. In this review, we will be focusing on sexual dysfunctions, their etiopathogenesis, and management from a dermatologist's perspective.

Inverted follicular keratosis is a rare benign tumor of the follicular infundibulum characterized by exo-endophytic growing. It is thought to be a rare variant of the seborrheic keratosis. The diagnosis of inverted follicular keratosis is generally established histopathologically because clinical differentiation from other lesions is difficult. Herein, we present one such rare case, successfully treated with topical 5% imiquimod cream.

Background: There is no uniform grading scale for objective assessment of premature canities that can serve as a reference. The aim of the study was to devise an objective and reproducible scoring system to assess the severity of premature canities. Materials and Methods: A cross-sectional study conducted from November 2011 to April 2013 in a tertiary care setup with 52 apparently healthy individuals with onset of premature graying of scalp hair before the age of 20 years. A new scoring system (Graying Severity Score, GSS) was devised to evaluate the extent of graying taking into account five representative sites from the scalp by two independent investigators and analysed for agreement. GSS ranged from 0 to 15 that was further graded as mild, moderate, and severe. Results: The highest total GSS attained was 13 and lowest was 4 (mean = 6.6 ± 1.97). Of the 52 patients 17 (32.69%) had mild, 32 (61.54%) moderate, and only 3 (5.77%) had severe GSS. Scores of both investigators were found to have good agreement. The intraclass correlation calculated by the two-way mixed model using the absolute agreement definition for the GSS was 0.967 (CI = 0.944–0.981; P = 0.000) and for GSS grade was 0.962 (P = 0.000). In the study subjects the frontal and the vertex regions were found to be the worst affected. Conclusion: GSS is a novel, numeric, objective, and reproducible tool for evaluation of premature canities that can be used to follow up and assess therapeutic response. Further large scale studies are recommended to optimize its utility.

Background: Skin infections caused by coryneform bacteria are common dermatological conditions. However, to the best of our knowledge, no studies are available on the clinical characteristics and epidemiological features of this group of disorders as one entity from India and abroad. Aims: To study the clinical and epidemiological features of coryneform skin infections Methods: A total of 75 patients presenting with clinically distinctive lesions of pitted keratolysis, erythrasma and trichobacteriosis to our hospital were included in the study. Cases were interviewed with particular emphasis on epidemiological features and the various clinical findings were recorded. Investigations like Gram's stain, Wood's light examination, 10% KOH scrapings, were done in selected cases to ascertain the diagnosis. Results: Pitted keratolysis was more common in the age group of 31-40 years (40%) with a male preponderance (76.7%), most commonly affecting pressure bearing areas of the soles with malodour (86.7%) and frequent contact with water (58.3%) constituting the most important presenting symptom and provocating factor respectively. Erythrasma affected both male and female patients equally and was more commonly detected in patients with a BMI > 23kg/m² (62.5%) and in diabetics (50%). All patients with trichobacteriosis presented with yellow coloured concretions in the axillae. Bromhidrosis (71.4%) and failure to regularly use an axillary deodorant (71.4%) were the most common presenting symptom and predisposing factor respectively. Conclusion: Coryneform skin infections are common dermatological conditions, though epidemiological data are fragmentary. Hyperhidrosis is a common predisposing factor to all three coryneform skin infections. Asymmetrical distribution of pits has been reported in our study. Diabetic status needs to be evaluated in all patients with erythrasma. Woods lamp examination forms an indispensible tool to diagnose erythrasma and trichobacteriosis.

Cutis verticis gyrata (CVG) is characterized by redundant skin on the scalp that exhibits deep furrows and convolutions. We report a 58-year-old male who presented with multiple raised asymptomatic skin-colored lesions over the chest and abdomen and features of CVG. Biopsy from the lesion confirmed the diagnosis of scleromyxedema. Scleromyxedema presents as diffuse thickening of the skin which underlies the papules. The hypertrophy and folding of the skin produces a gyrate appearance.

Sarcoidosis, a multisystem disease of obscure etiology, is characterized by the formation of noncaseating epithelioid cell granulomas in several organs or tissues. The diagnosis of sarcoidosis requires a compatible clinical picture, histologic demonstration of noncaseating granulomas, and exclusion of other diseases capable of producing similar histology or clinical features. The lung is the most commonly affected organ, but the skin is frequently involved. Sarcoidosis occurs worldwide and affects all ages and races with female predominance. Scalp involvement is decidedly rare among the myriad cutaneous manifestations of sarcoidosis. Alopecia is common in sarcoidosis and is generally scarring in nature. Annular sarcoidosis is a rare morphology and annular sarcoid of scalp is seldom reported. Herein we present a case of annular scalp sarcoid with systemic involvement and without alopecia.

Background: Health care–associated methicillin-resistant Staphylococcus aureus(HA-MRSA) are resistant to multiple antibiotics, therefore infections caused by them are difficult to treat resulting in high morbidity and mortality. While most of the research activities and public health initiatives are focused on HA-MRSA, the newly emerging pathogen, community-associated methicillin-resistant Staphylococcus aureus(CA-MRSA) is gaining in significance in respect to patient morbidity. There is a significant paucity of data regarding CA-MRSA in the developing parts of the world. Aim: To study the proportions of HA-MRSA and CA-MRSA infections among patients with culture-proven S. aureus infection and to find out how many of these patients showed presence of MRSA in nasal cultures of healthy contacts. Materials and Methods: Clinical details of 227 patients were recorded in the study, such as the duration and recurrence of the infection, history of antibiotic intake, and the presence of other medical illnesses. A pus swab was taken from each lesion and sent for culture and sensitivity. If the culture grew S. aureus, they were screened for methicillin resistance. A swab from the anterior nares of the healthy contact of each patient, whenever available, was collected and it was screened for MRSA. Results: Furunculosis was most common among the primary pyodermas (53/134; 39. 5%). Out of 239 pus culture samples obtained from 227 patients, 192 (84.58%) grew S. aureus; of these 150 (78.12%) were methicillin-sensitive S. aureus (MSSA), whereas 42 (21.98%) were MRSA. Out of the 42 MRSA isolated, 33 turned out to be CA-MRSA (78%) and 9 (22%) were HA-MRSA. Nasal swabs of healthy contacts of 34 MRSA patients were cultured. Out of them, two grew MRSA in the culture. Conclusion: The isolation rate of S. aureus was high in our study. Furthermore, our study, although hospital based, clearly indicated the substantial magnitude of the CA-MRSA problem in the local population.

Pigmented purpuric dermatoses (PPD), a group of vascular disorders with variable clinical picture is reported in all races and age groups with a male predilection. There are reports of mycosis fungoides manifesting as pigmented purpura as well as progression of PPD to cutaneous T-cell lymphoma. The diagnostic dilemma is compounded by PPD manifesting histological similarity to mycosis fungoides. Currently, it is believed that PPD with monoclonal T-cell population is more likely to progress to malignancy. We report a 31-year-old male patient who presented with the lichenoid clinical variant of PPD lesions that mimicked mycosis fungoides on histopathology. Gene rearrangement studies identified a polyclonal T-cell population. The patient responded to photochemotherapy, which is beneficial in both PPD and mycosis fungoides. Our case signifies the limitations of current diagnostic modalities in accurately distinguishing PPD from cutaneous lymphoma. Data on disease progression in similar cases may enable us to formulate better diagnostic definitions.

Verruciform xanthoma (VX) is an uncommon, benign, asymptomatic mucocutaneous lesion of an unknown etiopathology. It usually presents as a papule or single plaque with a verrucous or a papillomatous surface and pale yellowish to red in color. It occurs primarily on the masticatory mucosa of middle-aged individuals. We report a case of VX on the lip of a 59-year-old man. Histopathologically, VX is diagnosed by the presence of foam cells in the papillary region of the connective tissue. Differentiating a verrucous carcinoma from VX is important, especially in small superficial lesions, which may lead to inappropriate and excessive surgical intervention. Treatment of VX consists of simple surgical excision and recurrence is rare.

Cylindroma is a benign skin adnexal tumor of eccrine differentiation. Clinically, they are disfiguring lesions that can mimic a malignancy. Cylindromas can be single or multiple and commonly involve the scalp (turban tumor) and face. Multiple cylindromas can have a syndromic association as seen in Brooke–Spiegler syndrome and familial cylindromatosis. We present a case of non familial cylindroma of the face that clinically mimicked a basal cell carcinoma. The histopathology was confirmatory. Herein we also highlight the utility of a simple and inexpensive histochemical stain Periodic Acid Schiff in supporting the diagnosis.

We report a patient with Down's syndrome and neurofibromatosis who presented with a keloid, sebaceous cyst and acanthosis nigricans, along with dental and ophthalmological defects. The coexistence of neurofibromatosis type 1 and Down's syndrome which are two unrelated genetic conditions is itself a rarity.

Drawstring dermatitis is a type of frictional dermatitis that can result from a traditional tightly worn garments such as sari or salwaar-kameez. We report a 54-year-old female patient presented with lichen planus of the drawstring site that was confirmed histopathologically. This case is rare and demonstrates how sociocultural practices can influence the presentation of common dermatoses such as LP.
