1/12. Lichen planopilaris.P, a 20-year-old laborer displayed initial symptoms of the disease in question when he was 10 years old. Initially he had an asymptomatic progressive loss of hair on the scalp. A couple of years later he had mild to moderate pruritis, and the appearance of slate-blue eruptions on the scalp and elsewhere on the body. This resulted in a complete loss of hair on the vault of the scalp, which led him to seek specialist opinion. skin surface examination revealed the presence of grayish-blue acuminate follicular papules, disposed singly and in groups (plaques). The pilo-sebaceous orifices were conspicuously obliterated and filled by keratin plugs. Perifollicular erythema was a predominant feature on the scalp. The lesions were present over the scalp, around the neck, chest, back, axillae, groin and legs. Shiny atrophied scalp skin depicting scarring alopecia mimicking male-type baldness was a salient feature. In addition, it was studded with conspicuous acuminate papules in its center (Fig. 1a). The known nonhairy (glabrous) skin had classic lichen planus lesions (Fig. 1b). Hemotoxylin-eosin stained microsections prepared from typical lichen planus (LP) lesions over the abdomen and those of lichen planopilaris (LPP) of the scalp were simultaneously studied. The former revealed changes in the epidermis comprising of hyperkeratosis, increase in thickness of stratum granulosum, hydropic degeneration of the basal cell layer and band-like lympho-histiocytic infiltrate pressing against and invading the epidermis, while the latter revealed uniform atrophy of the epidermis and vacuolization of basal cells. The hair follicles were dilated and were filled with keratin plugs. In addition to fibrosis of the dermis, pigment laden microphages and lympho-histiocytic infiltrate was prominent. The follicles and the sebaceous glands were absent. However, arrectores pilorum and sweat glands were preserved (Fig. 2a,b).- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
2/12. Acute diffuse and total alopecia of the female scalp. A new subtype of diffuse alopecia areata that has a favorable prognosis.BACKGROUND: Although alopecia areata (AA) usually starts with focal lesions of hair loss and then presents several different clinical forms, AA may begin as diffuse hair loss. We examined 9 female patients who presented with acute, diffuse and total hair loss of the scalp and took a similar clinical course with a favorable prognosis. OBJECTIVE: To categorize such cases as a new subgroup of diffuse alopecia. methods: We studied 9 patients who showed acute, diffuse and total hair loss of the scalp within 1 month after their first visit to our hospital by comparing their clinical course, laboratory tests and histopathological findings with those of common, patchy AA, alopecia totalis or alopecia universalis. RESULTS: None of the patients had a background of systemic diseases or telogen effluvium. All the patients were female, and 8 of the 9 cases recovered cosmetically acceptable hair growth within 6 months regardless of steroid administration. The histology of he lesions was indistinguishable from that of AA except for a remarkable eosinophilic infiltrate. CONCLUSIONS: These cases can be categorized as a new subtype of inflammatory noncicatricial alopecia that is characterized by a marked female predominance, tissue eosinophilia and uniquely short clinical course. We suggest to name it 'acute diffuse and total alopecia of the female scalp (ADTAFS)'.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
3/12. Ulcerated juvenile xanthogranuloma of the scalp.A 7-month-old girl presented with a single rapidly enlarging thickly crusted lesion on her frontal scalp. histology was consistent with a juvenile xanthogranuloma (JXG) with ulceration and surface crust formation. Reports of ulcerating, crusted lesions of JXG are rare and the few reports have been confined to giant forms or those involving mucosal sites. This unusual presentation delayed diagnosis. Our report highlights the great variability in clinical presentation of JXG and is a reminder to consider this diagnosis in the differential of any lesion developing in an infant, particularly on the head, neck and upper trunk.- - - - - - - - - - ranking = 0.77731872133329keywords = upper (Clic here for more details about this article) |
4/12. Seborrhoeic dermatitis of the scalp--a manifestation of Hailey-Hailey disease in a predisposed individual?A 59-year-old man was found to have typical Hailey-Hailey disease of the back, neck and axillae. In addition, he had fine white scaling in the scalp and postauricular areas. Despite the clinical appearance of seborrhoeic dermatitis, a biopsy of his scalp showed prominent suprabasal epidermal separation with acantholysis. We propose that in a genetically predisposed individual, Hailey-Hailey disease can assume atypical and non-specific appearances.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
5/12. malassezia folliculitis on the scalp of a 12-year-old healthy child.malassezia folliculitis is a condition chracterized by itchy follicular papules and pustules with erythema. malassezia yeasts are the pathogens in this condition. It is mainly located on the back, shoulders, and chest. Presented here is a 12-year-old boy with malassezia folliculitis on the scalp. The case was found to be worthy of presentation because it rarely occurs in childhood and is rarely located on the scalp.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
6/12. scalp actinomycosis mimicking soft tissue mass.actinomycosis is a rare, subacute or chronic bacterial infection, characterized by localized swelling with suppuration, abscess formation, tissue fibrosis, and draining sinuses. It is caused by gram-positive, pleomorphic non-spore-forming, non-acid-fast anaerobic or microaerophilic bacilli of the genus actinomyces. In humans, actinomyces are often normally found in the oral cavity, the gastrointestinal tract and the female genital tract. Infections of the oral and cervicofacial regions are the most commonly reported cases. We present a case of subcutaneous actinomycosis, localized at the upper segment of the posterior neck space, with scalp involvement.- - - - - - - - - - ranking = 0.77731872133329keywords = upper (Clic here for more details about this article) |
7/12. Localized chronic pemphigoid of Brunsting-Perry. Ultrastructural localization of IgG and complement components.Immune electron microscopic data are presented of a typical case of localized chronic pemphigoid (LCP) of Brunsting-Perry. The peroxidase-antiperoxidase multistep method for the electron microscopic localization of immunoglobulins and complement components showed that IgG, C3, and C4 were distributed in the lamina lucida and on the undersurface of the basal keratinocytes. These findings support the concept that LCP, bullous pemphigoid, and benign mucosal pemphigoid are closely related diseases. Unlike in bullous pemphigoid, however, complement was occasionally found in this case of LCP beyond the basal lamina in the uppermost portion of the dermis. This finding may explain the occurrence of scar formation in LCP.- - - - - - - - - - ranking = 0.77731872133329keywords = upper (Clic here for more details about this article) |
8/12. Pyogenic versus pseudopyogenic granulomas.Surgeons are confronted daily with a myriad of skin pathology. Pyogenic and pseudopyogenic granulomas are certainly among the differential diagnoses to many nonhealing dermal lesions. This article revisits two types of vascularized lesions that are perhaps part neoplastic and part inflammatory/reparative. The differences clinically between these two types of lesions are few. The classical form generally is found along mucosal surfaces and upper extremities. The pseudopyogenic granuloma is more often found on the scalp and ears. Confirmation in their diagnoses is based strictly on their histological criteria. The management of these two types of lesions is identical. Excisional biopsies for all nonhealing lesions are warranted to rule out lesions with an ominous progression.- - - - - - - - - - ranking = 0.77731872133329keywords = upper (Clic here for more details about this article) |
9/12. A case of steatocystoma multiplex with prominent cysts on the scalp treated successfully using a simple surgical technique.The case described is a 35-year-old male with multiple cysts on the upper half of his body. This patient was diagnosed as having steatocystoma multiplex, based on clinical and histological findings. The lesions consisted of widespread and unusually prominent cysts, which were removed by a simple surgical technique using a dermatological trepan and artery forceps. We provide here a detailed description of the surgical procedures employed.- - - - - - - - - - ranking = 0.77731872133329keywords = upper (Clic here for more details about this article) |
10/12. Generalized infestation of a 3 1/2-year-old girl with the pubic louse.A 3 1/2-year-old girl had a Pthirus pubis infestation of the scalp, neck, eyelashes, back, and pubic area. The child's body, including the scalp, was treated with a 1% permethrin cream rinse formulation for 10 minutes. The treatment was repeated after 10 days. The eyelashes were treated by application of the permethrin solution with a cotton-tip swab.- - - - - - - - - - ranking = 1keywords = back (Clic here for more details about this article) |
