Rare paratesticular aggressive angiomyxoma with negative oestrogen and progesterone receptors in a male patient

Aggressive angiomyxoma (AAM) is a rare mesenchymal myxoid tumour localised to the pelvis and/or perineum in adult females in reproductive age group. AAM is very rare in males, with <50 cases described in literature, and involves scrotum, spermatic cord and perineum. It is slow growing, with a marked tendency for local recurrence after excision, but without metastatic potential. We present a rare case of a paratesticular AAM in a man aged 53 years. Tumour cells were immunoreactive for desmin, smooth muscle actin (SMA), vimentin, CD34 and were negative for S100. Unlike AAMs in females which express oestrogen receptor (ER) and/or progesterone receptor (PR) in >90% cases, the tumour cells in our case were negative for ER and PR, suggesting that the hypothesis that these markers play a role in tumour development and pathogenesis, does not apply in males. Androgen receptor positivity was noted in 2%–5% tumour cells.
