Which of the following subcutaneous mycoses may exhibit respiratory and cerebral forms? a. chromoblastomycosis b. mycetoma c. phaeohyphomycosis d. sporotrichosis

Hello, everyone. Welcome back. Our next question says a 45 year old man presents to the clinic with a chronic cough, shortness of breath and a recent onset of neurological symptoms including headaches and confusion. He has a history of gardening and occasionally suffers from minor skin abrasions. Imaging reveals lesions in the lungs and brain which of the following subcutaneous mycosis could most likely exhibit both respiratory and cerebral forms in this patient. A Chromoblastomycosis B mycetoma C phycomycosis or D sporotrichosis. So the key unique aspect here as our question says is that this form of fungal infection exhibits respiratory and cerebral symptoms so that can help us rule out our other answer choices. So our correct answer is going to be choice. C theo hyph mycosis. This is a mycosis caused by demas or darkly pigmented fungi which can occur in cutaneous subcutaneous subcutaneous and systemic forms and it can affect both the lungs and the central nervous system. When we look at our other answer choices, they're all forms of subcutaneous mycosis and that could you could be at risk of contracting wall gardening, but they wouldn't be likely to cause these respiratory and cerebral effects. So choice. A Chromoblastomycosis is a chronic infection of the skin or subcutaneous tissue and it's usually caused by what we call the traumatic implantation of fungi. So, an infection is a result of a cut in the skin. So as our patient has where he suffers minor skin abrasions while gardening, but it would not lead to respiratory symptoms or cerebral symptoms. So it's not our answer. Then. Choice. B miso Toma is a chronic granuloma, granulomatous fungal or bacterial infection of the skin or subcutaneous tissue. But it primarily affects feet. So again, not expected to cause respiratory and cerebral forms note also that both A and B are chronic infections, whereas we are told that this is a recent onset of neurological symptoms. Then finally, twisty sporotrichosis is a subcutaneous mycosis usually following skin trauma and it can affect the skin, the lymphatic system, sometimes bones and joints. So it can have these systemic effects but doesn't usually cause respiratory or cerebral effects. So, not our answer choice. So again, the unique key feature here is that this particular mycosis is causing both lungs and brain to show lesions and have symptoms. And again, the mycosis you would expect is choice C pheo hyph mycosis. See you in the next video.
