Clinical profile of recurrent vesicular palmoplantar dermatitis in children and adolescents.

Background: Previously known as dyshidrosis, recurrent vesicular palmoplantar dermatitis (RVPD) is presented as severe eruption of nonerythematous, symmetrical vesicles or bullae located along the lateral sides of fingers, on the palmar or plantar areas, and developing into a chronic and recurrent condition. Although very frequently observed on the hands, there are no specific studies about such eczema in children and adolescents.

Objectives: To report on the RVPD clinical profile in children and adolescents, and monitor the association of RVPD with seasonal variations, hyperhidrosis, atopy and nickel sulfate.

SQUAMOUS CELL CARCINOMA IN THE FOOT: CASE SERIES AND LITERATURE REVIEW.

Objectives: To report a case series of squamous cell carcinoma (SCC) in the foot, describing previous risk factors, surgical treatment, histopathological findings, and functional and oncological results.

Methods: Nine consecutive patients diagnosed with SCC of the foot were treated at a single institution and prospectively analyzed for risk factors related to the disease, surgical outcome, and histopathological, functional and oncological results. All patients had identifiable risk factors for SCC.

Exuberant pyoderma gangrenosum in a patient with autoimmune hepatitis.

Pyoderma gangrenosum is a rare neutrophilic dermatosis, which usually presents as ulcers with erythematous-violaceous undermined edges and a rough base with purulent or sanguinous exudate. It can be primary or associated with an underlying disease. However, rare cases of its association with autoimmune hepatitis have been described in the literature.

Pityriasis amiantacea: a study of seven cases.

Pityriasis amiantacea was first described in 1832. The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain.

[Not Available].

Squamous cell carcinoma (SCC) is the second-most common malignant cutaneous cancer, with 60% occurring in the head and neck region. Metastases are uncommon and imply a more conservative prognosis. This report describes a case of parotid-invasive, facial squamous cell carcinoma, highlighting the importance of its prognostic and therapeutic management.

Study of the histopathological types of cutaneous melanoma in Palmas-TO from 2001 to 2011.

Background: Cutaneous melanoma (CM) is considered serious for causing frequent metastasis, presenting high mortality, resistance to available therapies and incidences in laboring activity.

Objectives: To study the histopathological types of cutaneous melanoma in Palmas-TO from 2001 to 2011, according to risk factors, location of lesions, Clark levels and Breslow thickness.

Methods: A descriptive, retrospective and quantitative research in reports of the Serviços de Anatomia Patológica in Palmas (SAPP) and Registro de Câncer de Base Populacional de Palmas (RCBPP).

Sporotrichosis with bone involvement: an alert to an occupational disease.

Sporotrichosis is a subacute or chronic mycosis caused by a fungus of the genus Sporothrix, which is found in soil. It can be acquired by trauma to the skin. Bone and joint lesions are very rare.

Pulse therapy in pemphigus: report of 11 cases.

In this study, five cases of pemphigus vulgaris and two cases of pemphigus foliaceus were treated with cyclophosphamide pulse therapy associated with prednisone, resulting in the need for a smaller maintenance dose of prednisone. In three cases of pemphigus vulgaris and one case of pemphigus foliaceus, dexamethasone and cyclophosphamide pulse therapy associated with prednisone helped the lesions to heal more rapidly. Neither treatment however prevented the recurrence of the disease.

Hidradenitis suppurativa: retrospective study of 20 cases.

In this study, twenty cases of severe hidradenitis suppurativa are reported, mainly in non-white people and in axillary areas. Wide surgical excision has offered good results, although relapses have occurred at variable intervals in the follow-up period.

The risk of cutaneous melanoma in melanocytic nevi.

The data on melanoma associaed with melanocytic nevus are controversial. A longitudinal prospective study of 107 cases of cutaneous melanoma revealed that 9 (8.4%) cases were presumed to be linked to a precursor lesion, but only in 1 (0.

Cutaneous melanoma: a prospective study of 42 cases.

A prospective longitudinal study of 42 cases of cutaneous melanoma showed that: 71.2% of patients were between 50 and 79 years of age; 45.1% were male and 54.

Leukoderma punctata following topical PUVAsol treatment.

Two adolescent females and a girl, all with clinically diagnosed vitiligo, were treated with 0.2% 8-methoxypsoralen cream followed by exposure to solar ultraviolet light. One year later, they developed hypopigmented and achromic spots on the areas affected by the vitiligo.

[Case for diagnosis. Reticulate acropigmentation of Dohi].

Reticulate acropigmentation of Dohi is a rare dyschromic disorder of autosomal dominant inheritance. Most cases have been originally described in Japan. The case of a girl with lesions of typical distribution and morphology is reported.

Childhood vitiligo and thyroid disease.

The association of vitiligo / thyroid disease in childhood is debatable; 50 children with vitiligo and 40 without it were submitted to serum dosage of antithyroid antibodies and thyrostimulating hormone. One case (test group) and one control showed a serum titer of TSH above the normal limit; vitiligo did not represent a greater risk for thyroid disease.

Clinical study of the congenital melanocytic naevi in the child and adolescent.

Background: The classification of the congenital melanocytic nevus (CMN) and the magnitude of the risk of transformation into melanoma are still controversial.

Objective: To analyse the profile of the CMN in the child and teenager at IPPMG-UFRJ according to sex, skin colour, age, clinical type, locations and evolution.

Methods: Longitudinal study of retrospective and prospective cohort from 1994 to 2007.
