Primary nonessential cutis verticis gyrata with acne keloidalis nuchae.

Cutis verticis gyrata is a rare disorder characterized by redundant skin forming deep furrows and convolutions. It has been associated with several systemic and cutaneous disorders. We report a case of primary non-essential cutis verticis gyrata in association with acne keloidalis nuchae in a schizophrenic patient.

A retrospective comparative study of outcome with surgical excision and repair versus nonsurgical and ablative treatments for basal cell carcinoma.

BACKGROUND: There are few studies on basal cell carcinoma (BCC) from India. Long-term follow-up is available in only one study and the aesthetic outcome of treatment has not been evaluated in Indian patients. AIMS: In this retrospective study on BCC, we compared treatment failure, recurrence rates and aesthetic outcomes on long-term follow-up between surgical excision and repair, and nonsurgical and ablative treatments. METHODS: Records of patients with BCC treated in the dermatologic surgery clinic over the past 10 years were analyzed. Patients with histopathologically confirmed BCC who could be contacted were evaluated for recurrence, treatment failure, overall satisfaction and aesthetic outcomes by global aesthetic improvement scale. RESULTS: Out of 98 patients, 72 were contactable. Four patients received both nonsurgical and ablative treatments and surgical excision and repair sequentially and were excluded. The mean age of patients was 57.9 ± 15.8 years (24-90 years) and the male: female ratio was 1.6:1. The most common site involved was the face (72.1%) followed by trunk and scalp, and the most common type of BCC was the pigmented superficial type (33.8%), followed by the pigmented noduloulcerative type (16.2%). There was no significant difference between the groups in the number of high-risk cases. The mean follow-up period was 37.1 ± 31.4 (range, 4-120) months. Fifty one patients were treated with surgical excision and repair, and 17 with nonsurgical and ablative treatments (9-imiquimod, 5-cryotherapy, 4-radiotherapy). Treatment failure was seen in 5 (7.4%) patients, all in the nonsurgical and ablative treatments group (P = 0.0006). Recurrence was seen in 2 (2.9%) patients, both in the surgical excision and repair group (P > 0.05). Mean patient satisfaction was significantly higher with surgical excision and repair, though there was no significant difference in the Global Aesthetic Improvement Scale between the groups. LIMITATIONS: The sample size was low. Only telephonic and pictorial assessments were done where the patient could not come for follow-up. CONCLUSIONS: Surgical excision and repair was associated with better outcomes than nonsurgical and ablative treatments. Treatment failures and adverse events were high with nonsurgical and ablative treatments. The recurrence rate was low.

Lobomycosis: a therapeutic challenge.

Lobomycosis or lacaziosis is a chronic granulomatous fungal infection caused by Lacazia loboi. Most cases are restricted to tropical regions. Transmission is believed to occur through traumatic inoculation in the skin, mainly in exposed areas. It is characterized by keloid-like nodules. There are only a few hundred cases reported. The differential diagnoses include many skin conditions, and treatment is difficult. The reported case, initially diagnosed as keloid, proved to be refractory to surgical treatment alone. It was subsequently approached with extensive surgery, cryotherapy every three months and a combination of itraconazole and clofazimine for two years. No signs of clinical and histopathological activity were detected during follow-up.

Depigmentation therapies in vitiligo.

Depigmentation therapy in vitiligo is an option in those with extensive vitiligo who have failed to respond to medical therapy and have obvious cosmetic disfigurement due to intervening patchy pigmented areas. Various aspects of this therapy such as the cost, treatment time, course, permanency of depigmentation, side effects, and the possibility of repigmentation should first be discussed with the patient. At present, there is no ideal depigmenting therapy available, but many agents in the market have been in use for many years. Monobenzyl ether of hydroquinone (MBEH) is the mainstay and Food and Drug Administration (FDA) approved in USA but takes many months to depigment and is associated with local side effects and risk of repigmentation. Other agents which are also used are 4-methoxy phenol and 88% phenol. Physical therapies for depigmentation include Q-switched ruby and alexandrite lasers and cryotherapy. Second-line agents which can be explored for depigmentation include imatinib mesylate, imiquimod, and diphencyprone. Many possible experimental agents are being explored like various phenol derivatives, melanoma vaccines, interferon gamma, busulfan, etc. A major lacuna still exists in this area and a lot more research is desirable to give satisfactory cosmesis to these patients with extensive vitiligo.

Intralesional bleomycin in the treatment of cutaneous warts: a randomized clinical trial comparing it with cryotherapy.

BACKGROUND: Though not in regular practice, intralesional (IL) bleomycin has been used for the treatment of warts since the 1970s and on the other hand, till now cryotherapy is quite regularly used to treat warts. AIM: Our aim was to assess the evidence for the efficacy of IL bleomycin, in comparison with a control group of similar sample receiving cryotherapy, in the treatment of cutaneous warts. METHODS: Patients were randomized using computer-generated codes to receive either cryotherapy (double freeze-thaw cycle) or IL bleomycin (0.1% solution with concurrent anesthesia) for a maximum of four treatments 3 weeks apart and a maximum of five warts treated in each visit for both groups. Patients had their warts measured at base-line and with each return visit including a post treatment follow-up that was 8 weeks apart from last treatment taken. RESULTS: Of the 73 patients completing the study, 39 (53%) were treated with IL bleomycin and 34 (47%) were treated with cryotherapy. Out of 155 treated warts, 87 (56%) were treated with IL beomycin and 68 (44%) were treated with cryotherapy. The clearance rates in context of number of patients and number of warts were 94.9% and 97% for bleomycin and 76.5% and 82% for cryotherapy respectively (P < 0.05 by x(2) analysis and RR = 7.67). CONCLUSION: IL bleomycin injection was significantly more effective than cryotherapy for treatment of cutaneous wart.

Chronic zosteriform cutaneous leishmaniasis.

Cutaneous leishmanasis (CL) may present with unusual clinical variants such as acute paronychial, annular, palmoplantar, zosteriform, erysipeloid, and sporotrichoid. The zosteriform variant has rarely been reported. Unusual lesions may be morphologically attributed to an altered host response or owing to an atypical strain of parasites in these lesions. We report a patient with CL in a multidermatomal pattern on the back and buttock of a man in Khozestan province in the south of Iran. To our knowledge, this is the first reported case of multidermatomal zosteriform CL. It was resistant to conventional treatment but responded well to a combination of meglumine antimoniate, allopurinol, and cryotherapy.

Treatment of keloids and hypertrophic scars.

Clinicians always find it difficult to treat hypertrophic scars and keloids. Various treatment modalities are available. Intralesional corticosteroids, topical applications, cryotherapy, surgery, laser therapy, and silicone sheeting are the widely used options. Radiation therapy can also help in cases of recalcitrant keloids. Most recently, pulsed-dye laser has been successfully used to treat keloids and hypertrophic scars. There are no set guidelines for the treatment of keloids. Treatment has to be individualized depending upon the distribution, size, thickness, and consistency of the lesions and association of inflammation. A combination approach to therapy seems to be the best option.

Epidermolysis bullosa pruriginosa--report of three cases.

Epidermolysis bullosa pruriginosa, a genetic mechanobullous disease, is characterized by pruritus, lichenified or nodular prurigo-like lesions, occasional trauma-induced blistering, excoriations, milia, nail dystrophy and albopapuloid lesions, appearing at birth or later. Scarring and prurigo are most prominent on the shins. Treatment is unsatisfactory. We report three such cases: two of them first cousins, are described with history of blisters since childhood, followed by intensely pruritic lesions predominantly on the shins, and dystrophy of toenails, but no albopapuloid lesions or milia. Intact blisters were present in one case, and excoriations were seen in the other two. All of them showed encouraging response to cryotherapy.

Penicillamine induced pseudoxanthoma elasticum with elastosis perforans serpiginosa.

Long term D-penicillamine therapy, especially when used to treat Wilson's disease has been shown to cause elastosis perforans serpiginosa, pseudoxanthoma elasticum perforans and other degenerative dermatoses. We report a 23-year-old male patient who presented with multiple firm papules, nodules over the neck, axillae, front of elbows for five years. He was a known case of Wilson's disease on long-term treatment with penicillamine for the past 12 years. The papulonodular lesions were non-tender and some were discrete while others were arranged in a circinate pattern. There was central scarring of the skin within the circinate lesions. In addition, there were several small yellowish papules on both sides of the neck which eventually became confluent to form plaques. Histopathology confirmed the diagnosis of elastosis perforans serpiginosa and pseudoxanthoma elasticum. He was treated with cryotherapy (using liquid nitrogen through cryojet) for former lesions. The lesions showed remarkable improvement after five sittings. Now the patient is under trientine hydrochloride (750 mg twice daily) for Wilson's disease.

Disseminated Mycobacterium chelonae cutaneous infection: recalcitrant to combined antibiotic therapy.

A 25-year-old Thai housewife had a history of tuberculosis of the lymph nodes for six years that had been successfully treated with a course of anti-TB drugs. She developed several red, circumscribed, infiltrative plaques composed of umbilicated papules and pustules on her face and upper part of the body with cervical lymphadenopathy six months later. A pus smear from the lesion grew acid fast bacilli (AFB). Histopathological examination showed a mixed cell granuloma suggestive of infection. A T cell study showed a low CD4 count, and multi skin tests indicated cutaneous anergy. Culture from a biopsy specimen taken from the skin lesion grew M.chelonae; the cultures from blood, urine, and bone marrow. The lesions were not responsive to an anti TB drug given for 2 months based upon the results of the AFB positive pus smear before the culture and sensitivity reports were obtained. Since then the patient was treated with antibiotics according to the results of the sensitivity tests. A combination of amikacin and clarithromycin was started and hyperthermic therapy was later added with a partial response. Based upon the sensitivity test, kanamycin was introduced but had to be stopped because of ototoxicity. Sparfloxacin was used with an effective result but was discontinued for economic reasons. Finally, clarithromycin in combination with clofazimine and cryotherapy were given for a year before the lesions healed completely. It took a three years duration for the total course of treatment for this patient. She is still in remission after two years of follow-up period. This extensive cutaneous M.chelonae infection needed a prolonged combination of antibiotics with the addition of cryotherapy for the non-responsive lesions.

Tratamiento de la larva migrans cutánea (erupción serpiginosa): comparación entre albendazol y el tratamiento tradicional / Treatment of larva migrans cutanea (creeping eruption): a comparison between albendazole and traditional therapy

Objetivo: La erupción serpiginosa (ES), que es característica de las regiones tropicales y subtropicales, se está observando cada vez con más frecuencia en Italia. La presencia en las playas de animales extraviados infectados por nematodos de la especie Ancylostoma favorece el contacto entre la piel humana y el suelo infestado por la larva. Materiales y métodos: Describimos nuestra experiencia con 56 pacientes (13 tratados con crioterapia, 1 con tiabendazol y crioterapia, 6 con tiabendazol, 2 con albendazol y crioterapia y 34 con albendazol). Resultados: Se consiguió una curación rápida y definitiva en los 56 pacientes. Por tanto, la eficacia terapéutica de los distintos métodos utilizados es equivalente. Conclusiones: Creemos que albendazol debería considerarse como primera línea de tratamiento. Se tolera muy bien y la aceptación de los pacientes es buena (AU)
