  Abstract 

All-trans-retinoic acid (ATRA) has shown a significant improvement in the outcome of patients of acute promyelocytic leukemia and is associated with certain unique adverse effects. We report one such case of APL, who developed ATRA syndrome on day 7 of ATRA, which was relieved after ATRA withdrawal and dexamethasone therapy. Subsequently, with the reintroduction of ATRA, patient developed an unexplained fever which was followed by multiple painless ulcers over the scrotum on day 28 of ATRA. ATRA was withdrawn so as not to induce Fournier’s gangrene, and ulcers were closely monitored without the administration of systemic or local corticosteroids. Eventually, ulcers improved and completely healed by 4 weeks. This is a rare case report, wherein the same patient develops ATRA syndrome followed by scrotal ulcers, suggesting that the scrotal ulcer is a rare specific adverse effect of ATRA and its monitoring is required especially in patients having unexplained fever and leucocytosis.

  Introduction Top


Acute promyelocytic leukemia (APL) is a unique variety of acute myeloblastic leukemia (AML) characterized by the bone marrow infiltration with abnormal promyelocytes having PML-RARA fusion gene, leading to cytopenias and coagulopathy. A key component of APL management is the all-trans-retinoic acid (ATRA), which promotes maturation of promyelocytes into neutrophils. Among the many adverse effects of ATRA, ATRA syndrome is the most life-threatening adverse effect, occurring in one-quarter of patients on ATRA.[1] ATRA is also associated with scrotal ulcer as a specific cutaneous complication, which has been reported in extremely rare cases.[2],[3],[4],[5],[6]


  Case Presentation Top


A 33-year-old male presented with a history of epistaxis and fever since 3 days. On examination, he was normotensive with no hepatosplenomegaly. Laboratory studies showed hemoglobin 7.4 g/dL, leucocyte count 1.5 × 109 /L, platelet count <20 × 109 /L, prothrombin time 17.0s (normal 10–12s), activated partial thromboplastin time 29.9s (normal 30–36s), fibrinogen 3.0 g/L (normal 2.2–4.9 g/L), and D-dimer–4352 ng/mL (normal <250 ng/mL). Bone marrow examination and immunophenotyping analysis were consistent with the diagnosis of APL. PML/RARα (bcr1) by RT-PCR was positive. The patient was started on induction therapy with ATRA, 45 mg/m2/day, divided into two doses. Daunorubicin, 60 mg/m2/day for 3 days, was started on day 5 of ATRA (leucocyte count 6 × 109 /L). On day 7 of treatment with ATRA, the patient developed fever and it was followed by dry cough, respiratory distress, oxygen desaturation, and his CT thorax revealed bilateral lung infiltrates with subpleural sparing [Figure 1]. ATRA syndrome was suspected and ATRA was withheld and the patient was started on dexamethasone 10 mg twice a day. Fever subsided in 24h, respiratory distress settled in the next 4 days, dexamethasone was tapered, and ATRA was reintroduced after 6 days (day 17 of ATRA). After 2 days of reintroduction of ATRA, the patient developed a persistent unexplained fever in spite of being treated with appropriate antibiotics and antifungals. On day 28 of ATRA (leucocyte count 6 × 109 /L), the patient noticed painless ulcers over his scrotum. Examination of scrotum revealed four ulcers over the right hemi-scrotum, of which two were coalescing into a single ulcer. Ulcers were having black necrotic base with surrounding erythema and was indurated and nontender [Figure 2]. Bacterial and fungal stains and cultures from ulcer base were negative. ATRA-induced scrotal ulcer was suspected and ATRA was stopped. Subsequently, his fever subsided in 2 days and his scrotal ulcer started to heal and was completely healed by 4 weeks. Meanwhile, the patient achieved hematological recovery on day 33 of induction therapy and bone marrow showed complete remission, and hence ATRA was not restarted. Later, the patient received three courses of consolidation therapy with ATRA and daunorubicin, with no recurrence of differentiation syndrome or scrotal ulcer. He is currently on maintenance therapy and continues to be in remission.

  Discussion Top


ATRA is the standard line of treatment in cases of APL due to its high success rate of remission. Among the many side effects of ATRA, differentiation syndrome stands out as the most dangerous and life-threatening complication, reported in approximately 25% of patients.[1] Meanwhile, unusual and rare scrotal manifestations such as exfoliative dermatitis, ulceration, and Fournier’s gangrene have also been reported. Scrotal ulcers have been described only in few case reports, each having number of cases in a range of one to maximum four.[2],[3],[4],[5],[6] Even though there is a case series from Japan which mentions the incidence being 14% (4 of 29 patients),[6] due to scarcity of case reports, the exact incidence of the ATRA related scrotal ulcers is unknown.

ATRA syndrome is characterized by endothelial damage, capillary leakage, and systemic inflammation and infiltration involving internal organs by maturing neutrophils due to cytokine release,[1],[7] whereas the genital ulcers show neutrophilic infiltration and focal necrosis involving exclusively the skin of genital region.[5],[6] Even though both these adverse effects are thought to be due to the cytokine response of maturing neutrophils, it is still unclear whether genital ulcer is a part of the systemic inflammation producing ATRA syndrome or it is a specific adverse effect of ATRA. In our patient, after the reintroduction of ATRA, development of genital ulcer was not associated with recurrence of ATRA syndrome. This might suggest that genital ulcer is a specific adverse effect of ATRA rather than a part of ATRA syndrome.

ATRA-related genital ulcers are reported to appear only in the induction therapy, from as early as day 7 of induction to day 32, with a time lag between fever and genital ulcer development.[3],[4],[5],[6] Similarly in our patient, scrotal ulceration developed after 9 days of fever on day 28 of ATRA. Hence, APL patients with fever and increasing neutrophil count are to be monitored for genital ulcer development.

There are different approaches mentioned in the management of ATRA-related scrotal ulcer. Due to the possibility of progression of the genital ulcer into life-threatening Fournier’s gangrene, discontinuation of ATRA is advised by many,[6],[8],[9] although continuation of ATRA has not always shown worsening of genital ulcer.[3],[4],[5],[6],[10] Similar dilemma exists for the administration of systemic and local steroids in genital ulcer. In our case we took the former approach and ATRA was withheld and steroids were not administered. Eventually, the ulcer healed in 4 weeks with no evidence of further worsening. As our patient went into complete remission after 5 days of ATRA withdrawal, there was no major change in the APL management. Due to the lack of prospective trails for the management of ATRA related genital ulcer, it is better to tailor the approach according to the patient’s condition and watch for worsening of the ulcer.

Clinicians managing APL with ATRA are usually aware and hence patients are monitored for the ATRA syndrome due to its higher incidence and its association with high mortality if not intervened early. Similarly, rarely developing genital ulcers can also progress to life-threatening Fournier’s gangrene if it is not recognized early and intervened. However, genital ulcers are usually reported late or underreported due to the painless nature and its location. Hence, we feel that the clinicians must also be aware of this distressing rare cutaneous complication of ATRA, monitor and intervene early in the course of the disease.
