Introduction: Paratesticular rhabdomyosarcoma (RMS) is a rare aggressive tumor manifesting in children and young adults. This tumor derives from mesenchymal elements of the Tunica vaginalis, epididymis, and spermatic cord. It is a very metastatic lesion that can spread by lymphatics to the iliac, para-aortic nodes, lung, and bone. Case presentation: In this paper, the authors report a case of a 6-year-old child who presented to the clinic with a painless mass in the right side of the scrotum. The mass was misdiagnosed and had evolved rapidly over 2 weeks. The mass measured 16×32 mm on ultrasound, and therefore, an orchiectomy was performed. The histological examination of the excised tissue confirmed the diagnosis of paratesticular RMS. Discussion: Paratesticular RMS mainly presented as a painless mass in the scrotum. It was a very metastatic lesion that required an immediate management. However, a lot of cases of paratesticular RMS misdiagnosed at first time, which worsens the overall prognosis. Conclusion: Eventually, paratesticular RMS should be always taken into consideration when a scrotal mass is suspected. Due to its extremely serious metastatic potential, this condition requires early diagnosis and management. The treatment is currently well codified combining surgery, chemotherapy, and radiotherapy.

Mammary analog secretory carcinoma (MASC) is a newly described carcinoma with a molecular hallmark of ETV6‐NTRK3 fusion that promotes oncogenesis. While MASC histopathology was well‐studied in the literature, clinical behavior remains unstudied. We present a 22‐year‐old man with painless parotid mass, which was diagnosed as salivary gland cancer, MASC subtype.

Although treated appropriately, bladder cancer can recur and metastasize. We are reporting the case of a patient with a well‐cured bladder cancer who presented after 14 months with femoral pain which turned out to be a bony metastasis. The patient underwent surgical excision followed by chemotherapy.
