Phthirus pubis usually infests the pubis, groin, buttocks and perianal region. It can sometimes infest the thighs, abdomen, chest, axillae and beard. Eyelashes and eyebrows may be involved in children. The involvement of the scalp is very rare. We describe a case of P. pubis infestation located exclusively on the scalp in an adult woman. Neither lice/nits nor skin lesions were observed elsewhere, including eyebrows, eyelashes, axillae, pubis, buttocks and perianal region (the patient was hairless in the axillae and pubis)...

BACKGROUND: Infantile hemangioma (IH) is a common benign vascular tumor in children. In most cases, diagnosis is based entirely on clinical examination. When the diagnosis is uncertain, the first-line complementary examination is Doppler ultrasound. We report 4 cases of atypical infantile hemangiomas with delayed diagnosis and non-contributory imaging. PATIENTS AND METHODS: One child had congenital purple papules and nodules on the back of the foot, the second had inaugural ulceration of the buttocks, and the last two presented telangiectasia, either isolated or on an erythematous macula...

Background: Demographic studies of hidradenitis suppurativa (HS) in Western countries have found an association with the female gender and with co-morbidities, such as the metabolic syndrome. There are few studies in an Asian context. Objective: This study examines the characteristics of HS at a Singaporean institute and compares them to those of existing studies in the West. Methods: We report a series of 58 patients with HS seen at the University Dermatological Clinic, National University Hospital, Singapore, over a 13-year period between January 2004 and December 2016...

Skin aging is a complex process involving the additive effects of time-dependent intrinsic aging and changes elicited via skin's interaction with the environment. Maintaining optimal skin function is essential for healthy aging across global populations; yet most research focuses on lightly-pigmented skin (Fitzpatrick phototypes I-III), with little emphasis on skin of color (Fitzpatrick phototypes V-VI). Here, we explore the biomechanical and histologic consequences of aging in black African-American volunteers...

BACKGROUND: Skin aging is a complex biological process mixing intrinsic and extrinsic factors, such as sun exposure. At the molecular level, skin aging affects in particular the extracellular matrix proteins. MATERIALS AND METHODS: Using Raman imaging, which is a nondestructive approach appropriate for studying biological samples, we analyzed how aging modifies the matrix proteins of the papillary and reticular dermis. Biopsies from the buttock and dorsal forearm of volunteers younger than 30 and older than 60 were analyzed in order to identify chronological and photoaging processes...

The number of patients suffering from a sexually transmitted disease (STD) in Germany is rising steadily. Mostly MSM (men who have sex with men) are affected. We report the case of an HIV-positive patient with syphilis, in whom the implantation of permanent fillers into the buttocks and thighs, for cosmetic purposes, prevented standard therapy of syphilis by intramuscular penicillin administration. According to current guidelines intravenous ceftriaxone (2 g once daily) was administered instead.

BACKGROUND: With a life-time prevalence of 39%, low back pain (LBP) is one of the most common musculoskeletal disorders. Correct diagnosis of underlying causes is commonly seen as a prerequisite for successful therapy of LBP. Currently, there is no useful, non-invasive clinical test to diagnose painful lumbar zygapophyseal joints. Clinical tests with high diagnostic accuracy are therefore desirable. Inter-rater reliability is commonly seen as a prerequisite of test validity. The objective of this pilot study was thus to evaluate inter-rater reliability of new clinical pain provocation tests for diagnosing painful lumbar zygapophyseal joints...

Syringocystadenoma papilliferum (SCAP) is a benign tumor most commonly located on the head and neck area often associated with nevus sebaceus. In its usual location, the human papillomavirus (HPV) DNA and mutations in the RAS/mitogen-activated protein kinase signaling pathway have been detected in SCAP. We studied 16 cases of SCAP in the anogenital areas and buttock where this neoplasm is rare and attempted to find out whether SCAP in these sites have different histopathological and molecular biological features...

Dear Editor, A 29-year-old woman presented with abscesses on her buttock and leg attributed to flea bites inflicted 5 days earlier on return to Spain after 2 months in Guinea-Bissau. Ciprofloxacin was ineffective after 7 days, and she was referred for dermatologic evaluation. Examination revealed 4 round, indurated, erythematous-violet furunculoid lesions with a 1.5-2 mm central orifice draining serous material. She reported seeing larvae exiting a lesion, and we extracted several more (Figure 1). Parasitology identified Dermatobia (D...

We have read with great interest the case report recently published in Acta Dermatovenerologica Croatica by Boer and Mihajlovic (1), which describes a 33-year-old woman with an 18-year history of classic hidradenitis suppurativa (HS) who developed HS-like lesions at the position of the bra strap. We agree with Boer and Mihajlovic: according to our clinical experience, we are convinced that mechanical stress may contribute or, in some cases, result in the development of HS. In this regard, we will describe the case of a patient with a monster hernia who presented HS-like lesions on his abdomen corresponding to the perihernial skin area, suggesting that mechanical stress was an important pathogenic factor for HS development...

PURPOSE: During transanal pull-through (TAPT) for Hirschsprung's disease (HD), exposing the entire surgical anal canal (SAC) including the squamo-columnar junction, or anorectal line (ARL) is a crucial step for minimizing problematic postoperative bowel function. We present a hint for exposing the entire SAC. METHOD: Histologically, the ARL represents the junction of proximal unilayer columnar colorectal mucosa with distal stratified squamous epithelium and is the proximal limit of the SAC...

BACKGROUND: During the MRI examination, pediatric patients sleep under the sedation so that the image artifacts caused by the patient motion could be minimized. However, the sedative injection at the buttocks might cause a difficulty in the diagnosis of the buttock diseases using the MRI manifestations. OBJECTIVE: This study aims to explore the imaging characteristics of MR for the pediatric patients with the sedative injected at the buttocks in order to correctly diagnose the diseases...

Middle cluneal nerve entrapment neuropathy/neuralgia (MCN-EN) is a rare and potentially underdiagnosed etiology for chronic low back pain. Symptoms include pain in the buttock and posterior superior iliac spine area that is increased by activity and direct pressure over the area, and is "neuropathic" in nature. Previous case reports describe successful treatment of MCN-EN with nerve block and/or surgical decompression of the MCN. We present a case report detailing the first successful use of radiofrequency nerve ablation in treating MCN-EN...

A 60-year-old Japanese woman with severe osteoporosis presented with a history of right buttock pain and right lateral lower leg pain in an L5 distribution. She had been treated with methotrexate and methylprednisolone for rheumatoid arthritis (RA) and interstitial pneumonia. Computed tomography demonstrated a sacral stress fracture in the right sacral ala. The right L5 nerve root was compressed by the fracture site. This case is rare in that L5 radiculopathy was complicated by a sacral stress fracture. Clinicians should suspect sacral stress fractures when RA or osteoporosis is present in women who experiences lumbar pain and lumbar radiculopathy...

BACKGROUND: Despite existing guidelines and methods for standardized clinical photography in dermatology and plastic surgery, human skin exhibits exquisite site-specific morphologies and functions, and each body region can exhibit an individual pathologic phenotype. The aim of this work was to develop a standardized, representative and reproducible documentation of the multilocular hidradenitis suppurativa/acne inversa (HS) lesions, a disease mostly occurring in skin folds. METHOD: Optimal body positions for medical photography of candidate areas for HS involvement were evaluated...

Crusted scabies (CS) is a highly infectious hyperinfestation variant of scabies with up to millions of Sarcoptes scabiei mites present on the skin surface. Diagnostic clues include intense itching and thick crusting especially on the face, groin, and buttocks, although variable presentations may mimic other dermatoses. CS has been associated with immunosuppression including the human immunodeficiency virus (HIV) and lymphoreticular malignancies.1-3 A long latency period from symptom onset to diagnosis and appropriate treatment is often reported...

Calciphylaxis is a rare and life-threatening disease characterized by cutaneous arteriolar stenosis and vascular thrombosis leading to skin ischaemia and necrosis. While calciphylaxis occurs mostly in patients with end-stage renal disease, the disorder has been described in patients with normal renal function, namely non-uraemic calciphylaxis (NUC). A 41-year-old African-American woman presented with a painful ulcerative rash on her thighs and right buttock 2 months after undergoing an orthotopic liver transplantation...

BACKGROUND: Calcium hydroxylapatite (CaHA) is approved to correct moderate-to-severe wrinkles and folds and soft-tissue volume loss in the face and hands. More recently, subdermal injection using diluted CaHA has been used to improve skin laxity. OBJECTIVE: To review evidence for the safe and effective use of diluted CaHA in the face and body and provide best practice recommendations. METHODS: A global panel of expert aesthetic physicians convened to develop consensus-based guidelines for treating laxity and superficial wrinkles using diluted (ratio of 1:1) and hyperdiluted (≥1:2) CaHA...

A 42-year-old female patient was admitted with pruritic, tense bullous lesions on the neck, axilla, buttocks, groins, and to a lesser extent on trunk and limbs accompanied by oral mucosal blisters. Some of the skin bullae were grouped. (Figures 1 and 2) The disease had started 3 weeks prior to admission. The patient reported about contact with lamb (without using gloves) followed by a solitary erythematous nodule of the left palm about 4 weeks prior to the appearance of blisters. The diagnosis of orf had been raised clinically by a dermatologist and confirmed by the clinical regression of the nodule which had developed into an erythema at the time of admission...
