A rare case of subcutaneous fusariosis in an immunocompetent patient.

Fusarium species can cause diseases in immunocompromised patients, whereas have rarely been reported as pathogens in immunocompetent individuals. Fusarium oxysporum and F. solani species complex are the most frequent pathogenic species.

A different approach for identifying hypomelanotic macules in tuberous sclerosis complex.

Aim: Tuberous sclerosis complex is a neurocutaneous syndrome with an autosomal dominant pattern of inheritance and a high percentage of sporadic cases. One of the most interesting thing about tuberous sclerosis complex is the earliest skin manifestation represented by the hypomelanotic patches. These lesions may be difficult to diagnose.

Adnexal polyp in a newborn baby.

Birthmarks can frequently be seen in newborn babies, but their etiopathogenesis is often unclear. These lesions can be divided into three groups: vascular birthmarks, pigmented birthmarks, and birthmarks resulting in abnormal development. Some birthmarks may require further analysis and clinical follow-up in order to rule out underlying defects, malignant potential, or correlation with syndromic diseases.

Angles and geometric shapes, but not lines, in melanocytic lesions may be helpful in the clinical diagnosis of melanoma.

Background: Geometric shapes have been suggested to be found in malignant melanomas. We have observed a number of melanomas presenting with linear and incomplete angulated figures.

Objective: To verify the assumption that geometric shapes, a linear border and/or incomplete angulated figures may indicate a potential melanoma.

Clinically and/or histologically pigmented poromas in Caucasian patients.

Aim: Pigmented poromas are rarely reported and considered to be more common in non-white people and on non-acral sites. Objective of the present study was to report our cases of pigmented poromas with particular attention to the presence of clinical and/or microscopic evidence of pigmentation, their characteristics and the diagnostic pitfall with other pathologies.

Methods: All the histologically confirmed poromas observed from January 1994 to July 2012 were considered.

Observational study on the mitotic rate and other prognostic factors in cutaneous primary melanoma arising from naevi and from melanoma de novo.

Background: Melanomas can arise from naevi or appear de novo. The frequency or the effect of their origin on prognosis is still debated. Mitotic rate (MR) and ulceration of melanomas have been proposed as further new prognostic indexes.

Tinea capitis in the paediatric population in Milan, Italy: the emergence of Trichophyton violaceum.

Tinea capitis (TC) is the most common type of dermatophytosis in children. The epidemiology of TC depends on the geographical areas, and it changes over time. The aim of the study is to determine the incidence of TC and to identify the causative species in children observed at Dermatology Outpatient Department of the University of Milan, Italy, between January 2004 and December 2011.

Unusual sites for poromas are not very unusual: a survey of 101 cases.

Background: Poromas are benign adnexal tumours generally believed to be of eccrine origin, which usually develop on palmoplantar sites. However, it is thought that a percentage of poromas develop on non-palmoplantar or 'unusual' sites.

Aim: To review cases of poromas with reference to their clinicoepidemiological characteristics, paying particular attention to the those located on sites other than the palms and soles.

Basosquamous cell carcinoma: a survey of 76 patients and a comparative analysis of basal cell carcinomas and squamous cell carcinomas.

Background: Basosquamous carcinoma (BSC) is a rare epithelial tumor with a still confusing terminology. Since 2005 a more comprehensive and broader classification has existed.

Aim: To retrospectively review our cases of BSC according to the new WHO definition and to re-evaluate their clinical and demographic characteristics and the margin involvement after traditional surgical excision.

Comma hairs in tinea capitis: a useful dermatoscopic sign for diagnosis of tinea capitis.

Diagnosis of tinea capitis (TC) can be challenging for dermatologists, especially in noninflammatory TC caused by anthropophilic dermatophytes and in black patients, in whom erythema of the scalp is difficult to appreciate. The finding of a typical TC dermoscopic pattern may lead more quickly to a correct diagnosis.

Tinea corporis due to Trichophyton rubrum in a woman and Tinea capitis in her 15-day-old baby: molecular evidence of vertical transmission.

We report a case of a 40-year-old Caucasian woman who came under our observation with a 7-year history of a chronic erythematous scaly dermatitis, diagnosed as psoriasis, involving gluteal area and thighs, and treated with topical steroids without benefit. During pregnancy, a progressive worsening of her condition and an extension of cutaneous lesions were observed. Her newborn, a 15-day-old girl, presented a similar scaly and squamous lesion on her scalp.

Axillary basal cell carcinoma: additional 25 patients and considerations.

Background: Axillary basal cell carcinoma represents a rarely described occurrence in world literature.

Objective: To report our 14 years' experience of axillary basal cell carcinomas.

Methods: A review of Pathology department database is given.

Margin involvement and clinical pattern of basal cell carcinoma with mixed histology.

Background: Mixed basal cell carcinoma (BCC) has not been sufficiently and specifically studied.

Objective: The aim of this study was to estimate in adults the prevalence of mixed cases observed among primary BCCs and to compare clinical and anatomical features of mixed vs. single BCCs, with focus on the incomplete excision.

Spindle and/or epithelioid cells nevi in pediatric age: are they different from those of adults? A clinical review of 187 cases.

Aim: Spindle and/or epithelioid cells nevi represent the spectrum of a clinico-pathologic entity with different characteristics. Aim of the study is to provide information about the differences in characteristics of these nevi for different groups of age.

Methods: Two different groups are considered: younger than 15 years and older than 15 years.

Anatomic location of Basal cell carcinomas may favor certain histologic subtypes.

Background: Differences in age, site, and subtype exist in basal cell carcinoma (BCC).

Objective: To evaluate whether an independent association exists between the anatomic location and the histologic subtype of BCC.

Materials And Methods: A series of 3,254 BCCs was examined.
