Several terms, including mucus cyst of the penis, genitoperineal cyst of the medium raphe, parameatal cyst, hydrocystoma
and apocrine cystadenoma of the penile shaft, should be considered synonymous.
Other associated lesions were poikiloderma (n=3) (Figure 5), pyogenic granuloma-like lesions (n=1), bullous lesions and erosions (n=1), ulcers (n=2) (Figure 5), eccrine hydrocystoma
(n=1), acquired ichthyosis (n=2), cicatricial alopecia (n=3) (Figure 1), vitiligo (n=2), sicca syndrome (n=2), and salivary abnormalities (n=5).
The same in situ HPV DNA probes were performed using the same technique on 3 eccrine hydrocystomas
, 3 eccrine syringomas, 2 eccrine poromas, and 3 apocrine hydrocystomas
; none showed any positive staining.
