I have non-healing  round and oval shaped lesions/ulcerations on my neck for almost a year now.  A couple of them went away, but then new ones appeared; the tissue feels lumpy underneath.  They get covered by scabs, but do not heal.   Antibiotics and topical clindamycin seemed to help a little, but not much improvement had been observed.  When a skin sample was attempted to be cultured, no single specific bacteria was found. What can it be?? Please help!
Welcome to Chat Doctor. 1. The history suggest possible cause could be degenerated lymph nodal pathology.2. When lymph node enlarged and gets degenerative changes this kind of picture can be seen.3. Initially get an ultrasound examination done - that will help to assess the nature of the lump and its source and extent (relation with adjacent structures).4. An FNAC from the lesion to evaluate the cells involved in the process.5. The lymph nodal enlargement is seen after any systemic or localized infection / inflammation or any malignancy elsewhere in the body - which also need to evaluate - an ultrasound abdomen pelvis and a chest radiogram for a gross overview.6. On summation of all investigations and findings treatment will be given. Good luck. Hope I have answered your query.Anything to ask do not hesitate. Thank you.
