Male Genital Tract Quiz 3

Chimney sweepers and coal tar are associated with scrotal cancers. This is because chimney sweepers were historically exposed to coal tar, which contains carcinogenic substances. Prolonged exposure to coal tar can lead to the development of scrotal cancer, a type of cancer that affects the skin of the scrotum.

The mode of metastasis for the cancer on the frenum of the penis is through the lymphatics. Lymphatic metastasis occurs when cancer cells spread through the lymphatic system, which is a network of vessels and organs that help remove waste and fight infections. This mode of metastasis is common for cancers that are located near lymph nodes, as they provide a pathway for the cancer cells to spread to other parts of the body. In this case, the cauliflower-like appearance of the lesion suggests a potential malignancy, which could have spread through the lymphatic system.

The correct answer is epididymis. The patient's symptoms of painful tense testes and the progression of atrophy and fibrosis suggest a chronic infection. Tuberculosis (TB) is known to cause chronic infections, and it can affect various organs including the epididymis. In this case, the infection likely started in the epididymis and spread to the testes, leading to the observed symptoms and complications.

Phimosis refers to a condition where the tight prepucial ring of scar tissue prevents the foreskin from retracting over the penis. On the other hand, paraphimosis occurs when the phimotic prepuce is forcefully retracted, causing it to become trapped behind the glans and leading to swelling and potential medical complications.

In a patient with painless enlargement of the testes, the presence of granulomas in the seminiferous tubules suggests an autoimmune attack. Granulomas are small nodules formed by the immune system in response to chronic inflammation. In this case, the immune system mistakenly attacks the seminiferous tubules, leading to their enlargement. This autoimmune response can disrupt normal testicular function and potentially affect fertility.

Filariasis is a parasitic infection caused by filarial worms. Chylocele is a condition characterized by the accumulation of lymphatic fluid in the scrotum, leading to swelling. Scrotal elephantiasis, on the other hand, refers to the enlargement and thickening of the scrotal tissue due to chronic inflammation caused by the filarial infection. Both chylocele and scrotal elephantiasis are potential complications of filariasis, resulting from the obstruction of the lymphatic vessels by the worms.
