A 27-year-old man was diagnosed with a melanoma six weeks after being referred to the Dermatology Department by his General Practitioner (GP). His friends call his GP, concerned that he has withdrawn to his room over the last four weeks, has stopped playing basketball, has appeared to lose weight, and has missed his hospital appointments. There is a letter in his medical records informing the practice that he has missed two surgery appointments.
He later attends the surgery with a friend. He is dressed scruffily and doesn’t make eye contact during your conversation. His Patient Health Questionnaire-9 score is 15.
What is the most likely diagnosis?
