We report two cases of keratosis follicularis spinulosa decalvans in a Caucasian family involving a 28-year-old woman and her mother. This is an unusual family in that no male relatives are similarly affected. Secondly, both patients have no significant eye changes but quite extensive scarring alopecia. To the best of our knowledge this is the second reported family in the UK.

We report the case of a 75-year-old-woman who presented with bilateral scalp ulcerations and blindness, accompanied by severe headache and scalp tenderness, due to bilateral temporal arteritis without systemic involvement. A biopsy taken from the border of an ulceration showed evidence of giant cell arteritis. She was treated with oral prednisone, 60 mg per day. The ulcerations healed in a few weeks but the vision loss was irreversible. This case highlights for temporal arteritis the importance of accurate and timely diagnosis as well as the need for prompt therapy with systemic steroids in order to avoid major complications, namely loss of vision. It also demonstrates that scalp necrosis and ulcerations are skin signs associated with a poor prognosis.
Bacillary angiomatosis (BA) is a recently recognized bacterial infectious disease that is mainly seen in patients with the acquired immunodeficiency syndrome. BA has rarely been reported in immunocompetent individuals. A case of BA of the scalp in an immunocompetent patient, who was human immunodeficiency virus seronegative, is reported. The importance of differential diagnosis of this lesion is emphasized.
Arthritis is a well-recognized but uncommon accompaniment to several chronic cutaneous inflammatory conditions in which severe acne is one component. We report the case of a man with dissecting cellulitis of the scalp who developed severe peripheral and axial arthritis.
The Workshop on the morphological approach to hair disorders brought together a group of clinicians involved in hair biology research. Six speakers spoke on a range of topics that can be grouped broadly into a central theme. It summarizes the evolution of medical research. The section by Tosti and coworkers describes a patient with a new unique syndrome. The section by Ferrando and colleagues provides a framework in which patients with rare hair disorders can be classified. The section by Whiting tries to define the normal anatomy of the hair follicle and both horizontal and vertical sections. It is only when normal anatomy has been absolutely defined that pathological deviations can be recognized. The section by Sinclair and coworkers attempts to estimate the reliability of histological diagnosis so that its true value of pathology can be recognized. The section by Zlotogorski and coworkers shows how accurate clinical and histological definition of disease acts as the cornerstone for gene discovery techniques. Once a causative mutation is found and a gene product identified, then the biological consequences of the altered protein product can be studied and the impact of the abnormal molecular function on hair biology can be understood. It is hoped that improved understanding of hair disease will then lead to useful therapeutic interventions. The final section by Leroy and Van Neste highlights the difficulties of evaluating therapeutic interventions in hair loss disease and proposes a new technique.
BACKGROUND: Invasive fungal infections of the integument are relatively rare. In the immunocompromised patient, however, they may show an extremely aggressive biological behavior despite high dosed topical or systemic antifungal therapy. As the fungal tissue invasion usually reaches well beyond the area of clinical necrosis or other visible changes, standard surgical excision often proves to be inadequate, resulting in the need for repeated relatively wide excisions with the resulting substantial loss of initially healthy tissues. OBJECTIVE: To present the use of Mohs surgery as a safe and effective treatment modality for invasive fungal infections in a patient with a zygomycetes infection of his scalp. RESULTS: The micrographic excision of the highly aggressive fungal infection, the acute postoperative course, and the delayed reconstruction with a split-thickness skin graft were all well tolerated without complications. CONCLUSION: Mohs micrographic excision deserves serious consideration in the treatment of aggressive localized fungal infections.
Brooke-Spiegler syndrome is an autosomal dominant inherited disease characterized by the development of multiple trichoepitheliomas and cylindromas. We report two patients with Brooke-Spiegler syndrome whose scalp cylindromas were treated with a high-energy continous wave CO2 laser after debulking with bipolar scissors in one of the patients. The special feature in our report is the coexistence of three adnexal skin neoplasms in one case, and the close association of cylindroma and eccrine spiradenoma in the same lesion. We also support that debulking with bipolar scissors prior to laser therapy can be a technique of great benefit in large tumors.
BACKGROUND: There are fundamental concepts we use in managing surgical defects. Whether planning a primary closure or a local flap, we frequently modify the basic design to maximize aesthetic outcomes, taking into consideration a number of factors including the location of the defect and tissue availability. OBJECTIVE: We describe the stellate modified purse-string closure, a novel flap modification. METHOD: Report of an illustrated case. RESULT: A patient with vertex scalp defect was reconstructed using the stellate purse-string flap. CONCLUSION: Certain modifications of commonly used reconstructive techniques can be utilized in specific situations to enhance cosmesis. Advantages of this modification are discussed.
Erosive pustular dermatosis of the scalp is a rare condition of unknown etiology that usually occurs in the elderly and is characterized by pustules that appear on the scalp leading to scarring alopecia. The histopathology is not specific. Its onset has been related with previous trauma on the scalp. Only three cases after skin grafting have been reported. We describe a case of erosive pustular dermatosis of the scalp appearing on a split-thickness skin graft placed after excision of a basal cell carcinoma.
BACKGROUND: Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare disease manifested by the proliferation of morphologically distinct endothelial cells. OBJECTIVE: To illustrate by a case report the clinical and varied histopathologic findings of ALHE. METHODS: A 29-year-old woman presented with a clinical picture of ALHE but had several histologic features of angiosarcoma. RESULTS: Management of this patient included repeat biopsies of the lesions, excision of the involved areas, careful histologic examination of the entire specimen, and appropriate follow-up. CONCLUSION: ALHE may present with various histologic features. Knowledge of the spectrum of benign and malignant vascular neoplasms helps manage these challenging cases.
BACKGROUND: Actinic keratosis is an exceedingly common premalignant lesion that can develop into squamous cell carcinoma. There is an increasing prevalence of actinic keratosis with increasing age. Numerous treatment options are available for the treatment of actinic keratosis on the scalp. Although we know that atrophic skin heals slowly, one should be careful but should not hesitate to treat. OBJECTIVE: We present three patients with widespread actinic keratotic lesions on the atrophic bald scalp who received different treatments. METHODS: Patient 1 was treated with medium-depth chemical peel, patient 2 with cryopeel, and patient 3 with CO2 laser resurfacing. In all patients, the entire surface area was treated. RESULTS: Despite the different treatment methods used, all three patients had severely delayed wound healing as a complication. Remarkably, all patients had a prolonged period of re-epithelialization. CONCLUSION: Care has to be taken in patients with widespread actinic keratosis on the atrophic bald scalp when treating the entire surface area regardless the treatment modality.
Head lice is the most frequently occurring communicable disease, except for the common cold, among children in the United States. The impact on a family facing the challenge of head lice is tremendous, ranging from emotional to financial distress. Challenges also face the health care provider and school personnel. Many over-the-counter preparations and prescription products are available to combat head lice. With the alleged advent of pediculicide-resistant head lice, many other products and applications not necessarily intended to treat head lice are being recommended. The purpose of this article is to outline the products and procedures currently being utilized and to provide a starting point for treating head lice.
We report a case of myiasis caused by larvae of Dermatobia hominis in a 12-year-old boy. The infestation was acquired in Uruguay and was characterized by a single, large, inflammatory, nodular lesion located on the scalp. The lesion was accompanied by local pruritus and pain as well as diffuse headache and regional lymphadenopathy. From the lesion a single larva in stage III, of noteworthy size, was removed. Very few pediatric cases of myiasis due to D. hominis have been reported in the literature. Furthermore, as far as we know, just one adult case of myiasis caused by D. hominis acquired in Uruguay has been published.

The techniques used for diagnosis of head louse (Pediculosis capitis) infestation are a source of controversy. Most epidemiologic and diagnostic studies have been done using direct visual examination. The main objective of this study is to compare the efficacy of direct visual examination versus the louse comb method. The hair of each child was examined twice; one team used a screening stick and another team used a louse comb. Seventy-nine boys and 201 girls, 7-10 years old were examined. Examination with a louse comb found that 25.4% of the children were infested with both lice and nits, while another 31.3% had nits only. Boys were significantly less infested with lice and nits than girls (lice: 15.2 and 29.6%; nits: 21.5 and 35.4%, respectively). The infestation rate with lice and nits was significantly higher in children with long (68.9%) and medium-length (63.9%) hair than in children with short hair (44.0%) (p < 0.01). Direct visual examination found that 5.7% of the children were infested with both lice and nits, and another 49.0% with nits only. The average time until detection of the first louse was 57.0 seconds with the comb as compared to 116.4 seconds by direct visual examination. Diagnosis of louse infestation using a louse comb is four times more efficient than direct visual examination and twice as fast. The direct visual examination technique underestimates active infestation and detects past, nonactive infestations.
