ABSTRACT
To the best of our knowledge, we report the first case of recurring small red macules (petechia), exclusively localized on the gland secondary to fellatio in an adult man, who is on therapy with acetylsalicylic acid. No previous studies have been ever conducted on the possible onset of penis petechia after oral sex. Petechia are nonspecific cutaneous lesions appearing as circumscribed sub-epithelial hemorrhages, or appearing as small dark red or purplish spots as a result of capillaries rupture.

BACKGROUND: Seborrheic keratoses (SKs) may sometimes mimic benign and malignant skin tumors, and a biopsy can be necessary in order to rule out malignancy. METHODS: From the database of our pigmented lesion clinic, we evaluated the dermoscopic features of difficult-to-diagnose SKs that were biopsied between January 2010 and December 2014. RESULTS: SKs represented 3.8% of all excised lesions (161/ 4,182). Specifically, 91 (56.5%) were excised to rule out melanoma, 63 (39.1%) to rule out squamous cell carcinoma and 7 (4.4%) to rule out basal cell carcinoma. The following 10 global dermoscopic patterns were identified: multicomponent (32; 19.9%); reticular (24; 14.9%), characterized by an irregular pigment network; bowenoid (21; 13.0%); hairpin (19; 11.8%); keratoacanthoma-like (16; 9.9%); blue-nevus-like (15; 9.3%); lichenoid (6; 3.7%); hyperkeratotic (6; 3.7%); clonal (5; 3.1%); spitzoid (5; 3.1%). Furthermore, 12 SKs (7.5%) were not included in any of such patterns (not classified). CONCLUSION: Our results are in line with previous studies highlighting the dermoscopic variability of SKs. Although excised SKs may be classified into 1 of 10 repetitive dermoscopic patterns, a biopsy remains mandatory for those that cannot be clearly differentiated from common skin malignancies.

In the early 1990s a reduction in the rate of sexually transmitted infections (STIs) occurred, although recent years have seen an increase. The aim of this study was to examine epidemiological and clinical features of syphilis cases in patients with HIV infection. We reviewed the charts of HIV-infected patients referring to our centre in the period 2002-2011. Fifty of the 402 consecutive HIV-positive patients (12.4%) received a diagnosis of syphilis. An increasing trend in the number of syphilis cases was observed within the period of the study. Most patients with syphilis (64%) presented a latent syphilis of unknown duration. About half of these received a concomitant diagnosis of HIV infection. Men who have sex with men (MSM) were the largest group. In the years 2002-2011, the incidence of syphilis in HIV-infected patients increased in our centre, notably among MSM. There is an urgent need for campaigns aiming to prevent STIs.
