A 50-year-old male presented in February 2011 because of night sweets and cervical/ axillar lymph nodes. Biopsy revealed classical HL (CD30+, CD15+, EBV negative) and bone marrow was also positive, characterizing stage IV disease. He was treated with 6 cycles of ABVD and achieved complete remission (CR).
For two years he remained asymptomatic, and in April, 2013 he started to feel back pain and leg swelling. CT re-evaluation demonstrated an L3 vertebral lesion.

Slide: Case 14 (Area A)
A 69-year-old man, a retired engineer. He had undergone a radical prostatectomy with bilateral lymphadenectomy 7 years ago for Usual Acinar Adenocarcinoma of the Prostate (Gleason 3+3=6) at the AC Camargo Hospital. The surgery went normally, the resection margins and lymph nodes being free of neoplasia. The patient had no complementary treatment (radiotherapy and/or hormonal block).
In July, 2018, the patient presented himself at the BP-Beneficiência Portuguesa-as he had perceived the appearance of bilateral nodules in the inguinal region, but denying fever, weight loss or night sweats. He underwent ultrasound and tomography exams, which showed lymphadenopathies in the bilateral inguinal regions and in the left external iliac chain, measuring up to 2.5 x 1.3 cm in the latter. The imaging exam suggested the presence of neoplastic disease. These lymphadenopathies had not been evident in the prior exam, performed in 2014. The patient also referred to gastroesophageal reflux and urinary incontinence symptoms (sequelae of prostate surgery). He denied being a smoker and informed occasional consumption of alcoholic beverages (1-2 cans of beer per month). He also informed of his regular physical activity (physical conditioning and multifunctional gymnastics). A lymph node biopsy was made with a needle, but the anatomopathological exam was inconclusive, favoring reactional lymphoid hyperplasia, however with the recommendation to excise the lymph node for better appraisal. The excision of the lymph node was performed on August 14, 2018 (and the biopsy brought for discussion).

Slide: Case 18 (Area A)
A 47-year-old male was transferred to the Hospital de Clínicas de Porto Alegre (HCPA) from an emergency hospital due to lower back and lower limbs pain and progressive loss of strength in the lower limbs culminating in paraplegia. His symptoms had started three months earlier as only pain in the legs and in the lower back, which was attributed to «muscle pain» by the patient, who refused to look for help. Two months after the onset of the symptoms, he started to rapidly lose strength in the legs, and sought for canes to ambulate. One month later, he noticed a loss of 5 kilograms of weight, night sweats, and could not walk anymore, changing to a wheelchair without medical prescription. He was submitted to laboratory tests and a spine magnetic resonance imaging (MRI): the exams showed thrombocytopenia, hypoalbuminemia, increased serum creatinine and urea, increased thyroid-stimulating hormone (TSH), and low complement, and so empirical antibacterial treatment with piperacillin plus tazobactam was started. The spine MRI showed only disc protrusions and partial compression of the dura in L2, L3, L4, L5, and S1, to which the lumbar and leg pain were attributed. The patient was then referred to the HCPA for further investigation.
At admission, no pulmonary or cardiac alterations were found in the physical exam; the patient was oedematous in the lower limbs and in the scrotum; strength in the upper limbs was normal but was only grade 2 in the lower limbs; sensibility to touch, pain, and vibration was normal in all the four limbs. The cutaneous-plantar reflex was absent bilaterally. An arterial gas analysis was normal but for the increased lactate (3.1 mg/dL), and the hypothesis of sepsis due to urinary tract infection was made, so intravenous meropenem was started.
In the next day (D1), the patient presented tachycardia and dyspnoea, and, after 1.5 litre of Ringer lactate solution was infused with no alteration in the clinical parameters, he was transferred to the ICU. By this time, he was having auditory and visual hallucinations, and new blood exams were: lactate 3.1 mg/dL, sodium 131 mg/dL, urea 70 mg/dL, creatinine 1.72 mg/dL, aspartate-transaminase (AST) 62 IU/dL, and gamma-glutamyltransferase (?GT) 295 IU/dL. Norepinephrine infusion was started; a bedside thorax ultrasound showed an image compatible with atelectasis or consolidation in the left lung, and an abdominal computed tomography (CT) showed a 2.0 x 1.9cm mass in the right adrenal gland.
In the D3, blood tests showed platelets of 40,000/mm³, and a lumbar puncture showed increased protein (171mg/mL), normal glucose (35mg/mL), and increased leukocytes (19 cells/mm³, 92% lymphocytes), but was negative for Cryptococcus sp., other fungi, and acid-fast bacilli.
In the D5, a thorax CT showed left pleural effusion of approximately 500mL, and a thoracentesis was performed, with bright yellow transudate negative for both acid-fast bacilli and Epstein-Barr virus (EBV).
In the D6, an electroneuromyography (ENMG) diagnosed symmetrical severe sensitive and motor axonal polyneuropathy, predominating in distal motor axons. In the same day, the patient had a bowel movement for the first time since hospitalization, even with the use of laxatives and enema. Meropenem was suspended due to clinical inefficacy.
In the D7, a bone marrow biopsy was performed. In the same day, the patient’s blood pressure started to drop, and haemodynamic stability was achieved only with continuous infusion of 22mL/h of norepinephrine.
In the D8, the patient began again to be dyspnoeic and tachypnoeic, and thus was reintubated. Blood tests showed 21,000 platelets/mm³ and 19,000 leukocytes/mm³ with 5% rods. Antibiotics (vancomycin and meropenem) were reinitiated.
In the D9, the patient had a distended abdomen with intraabdominal pressure of 13mmHg; an exploratory laparotomy was performed, and a Meckel diverticulum was resected at 70cm before the ileocecal valve. The surgeons also found hepatosplenomegaly. Blood tests showed 18,000 platelets/mm³, and an arterial blood sample found pH of 7.11, pCO2 of 30mmHg, HCO3- of 9 mEq/L, pO2 of 147mmHg, and lactate of 15mmol/L. Continuous haemodialysis was initiated.
In the D12, the patient needing increasing concentrations of continuous norepinephrine to tolerate haemodialysis and showing no improvement in his general condition, the medical team and the family agreed to define the case as terminal. Haemodialysis and vasoactive drugs were suspended. The patient passed away in the night of D12 to D13, and, upon family agreement, was referred to the Service of Pathology for autopsy.
