ABSTRACT
A rare case of T cell acute lymphoblastic leukemia presenting with loss of vision, parotid swelling, hematuria and acute renal failure has been presented in a 40-year-old male. Acute T cell Lymphoblastic Leukemia should also be kept in differential diagnosis of hematuria, acute renal failure and loss of vision.
Keywords: Acute Renal Failure; Acute T Lymphoblastic Leukemia; Adult; Hematuria; Parotid Gland Enlargement; Ocular Manifestation
1. Introduction
A patient with acute leukemia (AL) usually presents with features of fatigue, bone pain, anemia, neutropenia, fever, weight loss and thrombocytopenia leading to skin and mucosal bleeding [1,2]. A patient may also present with hepatosplenomegaly, lymphadenopathy, sore throat, bronchopneumonia, mediastinal mass, renal stone and sternal tenderness [2,3].
Acute renal failure and hematuria as a primary manifestation of acute leukemia are very rare. Acute renal failure is attributed to acute tubular necrosis, nephrotoxic drugs, urate nephropathy, gout, tumor lysis and malignant infiltration [4-8].
We are reporting a case of T-ALL which presented with sudden loss of vision, hematuria, bleeding nose, parotid swelling and renal failure. This case is being presented because of rarity.
2. Case Report
A 40-year-old male, presented with anorexia and sudden loss of vision 4 months back for which he consulted a private physician and treated, the particulars of the treatment were not available. About 2 months later he developed bleeding nose, parotid swelling, petechial hemorrhage, nausea, vomiting, swelling of eyelids and hematuria. He was again treated by private physician but symptoms were not relieved, for which he was referred to our nephrology department. Clinically the patient was suspected to have rapidly progressive renal failure due to vasculitis.
On examination, he had mild anemia, mild hepatosplenomegaly. In ultrasonography, there was hepatosplenomegaly, renomegaly and nephrolithiasis. His urine examination revealed 3+ proteinuia, plenty of RBC’s (100 - 150/HPF) and WBC (80 - 100/HPF) with raised blood urea, uric acid and serum creatinine. Hematological investigations revealed low hemoglobin (10.1 gm/dl), thrombocytopenia (platelet count 38,000/cumm) and high total count (100 × 103/µl). His peripheral blood and bone marrow smears showed picture of acute lymphoblastic leukemia with mixture of small and large blast cells with scanty amount of cytoplasm, variable size and shape of nuclei with indentation, coarse chromatin and 1 - 2 nucleoli. Blast cells were negative for Sudan black and PAS stain (Figures 1 and 2).
Renal biopsy revealed only 3 to 4 glomeruli which

were normal in size and cellularity but with mild increase of mesangial matrix was noted. Tubules revealed swelling of tubular epithelial cells, clear appearing cytoplasm and vesicular nuclei and necrosis. Some tubules contained immature cells. Interstitium was heavily infilterated with large uniform size immature lymphocyte like cell with very scanty non visible cytoplasm and dark nuclei with coarse and opened chromatin (Figures 3 and 4). Blood vessels did not show any abnormality.
Immunophenotyping of leukemic cells on kidney biopsy revealed that immature cells were negative for myeloperoxidase (MPO) (Figure 5), CD13, CD19, CD20 and CD79a but almost all the cells were strongly positive for CD3 antigen (Figure 6) and CD7. Ultimately patient was diagnosed as a case of acute T cell Lymphoblastic Leukemia and chemotherapy was started but he died after 10 days of diagnosis.
3. Discussion
Acute renal failure (ARF) and hematuria may occur in
Figure 3. Acute T cell lymphoblastic leukemia. Immature cells are large, irregular, have fuzzy outline infiltrating whole interstitium. Focal necrosis and proximal tubules are seen [H&E ×400].
Figure 4. PAS stain of same case. Glomerulus is enlarged but normal in cellularity. Malignant lymphocytes are PAS negative [PAS stain ×400].

both acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) [6,8]. Renal failure is a rare manifestation of acute leukemia. A study [8] reported a case of AML who presented with acute renal failure,

bilateral ureteral obstruction, and pelvic mass. His peripheral blood showed 63% myeloblast. This patient died on 17th day after chemotherapy.
Another study [9] reported a case of ALL who presented with ARF and enlargement of kidney and liver. Histopathology of kidney and liver showed infiltration by lymphoblasts.
Suriya and Aleem 2010 described 2 cases of AL in which one was Pre B ALL and another was of AML M4. Both presented with gross hematuria, loin pain, low grade fever and thrombocytopenia. Both cases showed remission after therapy.
Our case is a rare by constellation of manifestations, initially by loss of vision followed by parotid swelling, epistaxis, petechial hemorrhage, hematuria and then acute renal failure. Delayed appearance of ALL may occur. One study [6] also reported a case of ALL in a child who initially presented as hemolytic uremic syndrome and after one month he developed typical features of ALL.
Patient of AL may also present with Bell’s palsy and renal enlargement along with renal failure [10].
Parotid gland enlargement in ALL is very rare. Agarwal et al. 2005 [11] reported 2 cases of B ALL in 23 year and 15 month old boy who presented with pallor, hepatosplenomegaly, lymphadenopathy, thrombocytopenia with parotid gland enlargement. Lymphoblasts in peripheral blood were CD10 positive.
Acute T ALL is still rare disease. It accounts for 15% - 20% cases of ALL. The blasts are PAS negative but acid phosphatase CD3, CD2 and CD7 are positive. T-ALL has got high incidence of CNS manifestation and mediastinal mass and have poor prognosis [2].
Sudden loss of vision was the primary and initial manifestation of this case. Leukemia may involve ocular tissue either by direct infiltration of retina or vitreous, hemorrhage, ischemia or toxicity due to various chemotherapeutic agents, infection due to immunosuppression or direct leukemic infiltration [12]. In our case hemorrhage was one of the causes. Since no biopsy was done it is difficult to predict direct infiltration.
4. Conclusion
Thus we conclude that T-ALL is to be kept as a cause of ARF with loss vision or parotid swelling in any age group.
