I cannot tell you if this lump and your abnormal blood test are related, because I cannot examine you. The back of the neck is a common place for skin cysts that can become inflamed and infected (epidermal inclusion cysts), as well as lipomas, which are benign fatty growths. Lymphoma is not diagnosed with a blood test. Instead, it is diagnosed by performing a biopsy of enlarged lymph nodes.
