Pathologists who find ectopic glands on the glans and/or on the prepuce, often describe them as Tyson's glands. In this regard, the term Tyson's glands can be replaced by two different descriptive expressions: papillomatosis corona penis and ectopic sebaceous glands. A 15-year old Caucasian male patient presented to our Institute with multiple and asymptomatic circular skin colored-to-yellowish papules at the level of the foreskin, also affecting the shaft of the penis, where they assumed a linear feature.

Epidermolytic hyperkeratosis is a histological reaction pattern seen in a variety of disease processes, including epidermolytic ichthyosis, Vorner's epidermolytic palmoplantar keratoderma, epidermal nevus, and solitary epidermolytic acanthoma. Here we present the case of a 59-year-old woman with multiple asymptomatic papules on her vulva. Clinical differential diagnoses included condyloma acuminata, seborrheic keratoses, bowenoid papulosis, adnexal tumors, and papular acantholytic dyskeratosis. Read More

Penile intraepithelial neoplasia (PIN), or penile squamous cell carcinoma in situ, is a rare disease and may be associated with high morbidity and mortality. In an attempt to avoid surgical intervention, which may result in poor cosmetic and functional outcomes for patients, many non-invasive treatments have been trialled with variable success rates. This review summarises the available literature describing the use of topical imiquimod for PIN. Read More

Traumatic neuromas are tumors resulting from hyperplasia of axons and nerve sheath cells after section or injury to the nervous tissue. We present a case of this tumor, confirmed by anatomopathological examination, in a male patient with history of circumcision. Knowledge of this entity is very important in achieving the differential diagnosis with other lesions that affect the genital area such as condyloma acuminata, bowenoid papulosis, lichen nitidus, sebaceous gland hyperplasia, achrochordon and pearly penile papules.

Bowenoid papulosis (BP) corresponds to an in situ squamous cell carcinoma (SCC) located in the anogenital region. It is related to HPV, and presents with gray-brown elevated papules or plaques. A biopsy is needed to confirm the diagnosis; however, dermoscopy may be useful to differentiate this disease from other conditions, such as genital warts, seborrheic keratosis and lichen planus.

Human papillomavirus (HPV) infection has been demonstrated in some of the nonmelanoma skin cancers as well as in precancerous lesions. Multiple infections of mucosal high-risk HPV may contribute to the onset of digital Bowen's disease through, if any, digital-genital transmission. We screened for the presence of the mucosal HPV DNA in patients with extragenital Bowen's disease (n = 30), squamous cell carcinoma (n = 11), bowenoid papulosis (n = 9), verrucous carcinoma (n = 1), actinic keratosis (n = 5), and basal cell carcinoma (n = 5).

Anogenital malignancies and premalignancies are an important personal/public health problem due to their effects on individuals' physical, mental, and sexual health. Also, due to their etiological association with human papillomavirus (HPV) infection, anogenital malignancies and premalignancies constitute an immense public health burden. In addition to HPV infection, immunosuppression, HIV infection, chronic dermatoses, such as lichen sclerosis, previous radiotherapy and chemotherapy treatments, and smoking, are the other important etiopathologic factors in the development of anogenital malignancies and premalignancies.

Human papillomavirus (HPV) incorporates high-risk HPV (hrHPV) and low-risk HPV (lrHPV) subtypes according to its contribution to oncogenesis. Different HPV subtypes could regulate the cell cycle of infected cells at different levels. To date, the expression of cyclin D1 and cyclin E in Bowenoid papulosis (BP) tissues and its association with HPV infection still remains elusive. Read More

Photodynamic therapy (PDT) with methyl aminolevulinate (MAL) has been suggested as a useful treatment option in a number of skin tumors, other than approved indications, and infections. However, evidence is poor because it is mainly supported by isolated case reports or small case series, often with conflicting results. To assess the effectiveness, tolerability and safety of off-label MAL-PDT in daily clinical practice in 20 Italian hospitals, a retrospective observational study of medical records of patients treated for off-label oncologic and infectious skin conditions was carried out.

Human papillomaviruses (HPVs) are small DNA viruses of the papovavirus family, with more than 100 types already described. Their importance in human disease cannot be overemphasized because these agents are among the most common pathogens in cutaneous infectious diseases and are very important in a subset of predominantly, but not exclusively, genital squamous-cell carcinomas. HPVs can be associated with a variety of cutaneous as well as mucosal manifestations. Read More

Anogenital warts (condylomata acuminata) are the most common lesions presented in men, however, during the last decade the other HPV-associated exaggerated lesions such as condylomata plana, penile, scrotal, and anal intraepithelial neoplasias, as well as the penile, urine bladder and prostate cancer have been studied somewhat more extensively. The clinical variations might range from clinically invisible, asymptomatic lesions to the bizarre forms of giant condyloma of Buschke-Löwenstein type, including Bowenoid papulosis, Mb. Read More

The inherent longetivity of stem cells causes them to be susceptible to multiple genetic hits. Thus, it is not surprising that stem cells are implicated in the etiopathogenesis of select cutaneous neoplasms. However, most studies to date are restricted to the use of a single marker (p63, cytokeratin-15 or cytokeratin-19) and do not appear to compare distribution of stem cell markers in a spectrum of cutaneous in situ versus invasive epithelial malignancies.
