Any differential diagnosis ideas based on
this presentation, thus far?

 1) hypoglycemia-corrected in ER
 2) hypercalcemia
 3) gen weakness
 4) hx prostate ca- review of old outpt labs – PSA 0.33 (9/20)
 5) elevated lft

 F/u w PCP- pt referred as outpt to heme/onc. Hypercalcemia w/u.
Ace level <5. Ionized Ca2+ 1.74. PTH 88*. After labs obtained endo eval
ordered.
 Admitted again on 2/3/21 – Dehydration, hypercalcemia noted and sl. chest pain.
R/o ACS w/u initiated and CTA done in ER. Pt. had not yet seen heme/onc as
outpatient – consult done. PTH ordered and resulted normal of 61 noted. ESR – 2.
Hemoccult for blood- negative. PSA recheck 0.24. A stable pulmonary nodule
was found on CT of the chest and nonspecific adenopathy to the chest and abd
noted. There was a large retroperitoneal lymph node noted.
 Any further ideas?

 Retroperitoneal bx done- revealed Large B-Cell Lymphoma of Follicular Origin
