A doctor has provided 1 answer

Enlarging cyst: A moveable lump in left armpit not nodal in origin. Most likely skin appendage. Common source is an enlarging sebaceous cyst filled with necrotic sebaceous material. At times a sweat gland tumor can look this way. Have lesion checked to see if it is cystic and if so the lesion with capsule must be removed by excision. If not cyst then evaluation as to need for bx must be made.
