Congenital leukemia cutis with subsequent development of leukemia

A Favourable Outcome in a Congenital Leukaemia Patient With Unique Cytogenetic Abnormalities

Congenital leukaemia (CL) is an exceptionally uncommon hematologic malignancy originating intrauterine and is typically associated with an unfavourable prognosis. The present case is a seven-day-old Malay baby girl who presented with mild fever and hepatosplenomegaly. She was initially treated as neonatal sepsis however subsequent investigations with bone marrow, trephine biopsy and immunophenotyping were consistent with B acute lymphoblastic leukaemia. The peripheral blood smear showed the presence of 90% blast cells. Cytogenetically, she harboured an unusual complex karyotype, 46,XX,der(5) t(5;15)(p15;q15),del(7)(q33q35)/47,idem,+2.ish t(5;15)(wcp15+)+22(wcp22+).  This rare case with extremely atypical cytogenetic findings is being brought to light since the patient responded favourably to the standard chemotherapy Interfant 06 protocol, during which she obtained many episodes of remission, and she still survives after three years of treatment. Despite that, she carries del(7), which is normally associated with adverse outcomes in myeloid disorders, but not in lymphoid disorders; the existence of t(5;15)(p15;q15) could be the element that contributes to her fortunate outcome. Although trisomy 22 is identified as a clonal abnormality, its significance in her case and lymphoid disorders remains unknown and requires further investigation.

[SFCE harmonization workshops: Neonatal acute myeloid leukemia]

Neonatal acute myeloid leukemias (AML) occurred within the first 28 days of life and constitute only a small proportion of all AL. They are distinguished from leukemias of older children by their clinical presentation, which frequently includes cutaneous localizations ("blueberry muffin rash syndrome") and a leukocytosis above 50 ×109/L. This proliferation may be transient, causing a transient leukemoid reaction in a background of constitutional trisomy 21 ("Transient Abnormal Myelopoieseis" or TAM) or Infantile Myeloproliferative Disease in the absence of constitutional trisomy 21 ("Infantile Myeloproliferative Disease" or IMD). In cases of true neonatal AML, the prognosis of patients is poor. Overall survival is around 35 % in the largest historical series. This poor prognosis is mainly due to the period of onset of this pathology making the use of chemotherapy more limited and involving many considerations, both ethical and therapeutic. The objective of this work is to review this rare pathology by addressing the clinical, biological, therapeutic and ethical particularities of patients with true neonatal AML or transient leukemoid reactions occurring in a constitutional trisomy 21 (true TAM) or somatic background (IMD).

Leukemia cutis revealing relapse of a chronic myeloid leukemia: A case report

Key Clinical Message

Clinical presentation of leukemia cutis (LC) is polymorphic and can reveal a malignant hemopathy. More commonly described in cases of acute myeloid leukemia (AML), LC can also occur in case of chronic myeloid leukemia (CML).

Abstract

Leukemia cutis is a rare form of extramedullary feature of malignant hemopathy, seldom associated with CML. Its clinical presentation is pleiotropic and differential diagnosis is broad. It relies on clinical and typical histological and biomolecular concordance. Once confirmed, treatment is based on that of the primary condition. We present a case of a leukemia cutis revealing a relapse of a CML successfully treated by tyrosine kinase inhibitor.

Aleukemic congenital leukemia cutis preceding monocytic leukemia with favorable outcome: A case report

A newborn girl had typical "blueberry muffin" skin lesions, which shows histopathologic features of monocytic leukemia cutis. The systemic leukemia was demonstrated after one month of life. She was treated by chemotherapy, including induction and three consolidation cures, according to the ELAM02 protocol, which led to complete remission. This case report with congenital form of AML5 cutaneous localization, preceding systemic involvement, with a 5-year follow-up and positive outcome is remarkable.

Leukemia Cutis-The Current View on Pathogenesis, Diagnosis, and Treatment

Leukemia cutis (LC) is defined as the leukemic infiltration of the epidermis, the dermis, and the subcutaneous tissue. Leukemia cutis may follow or occur simultaneously with the diagnosis of systemic leukemia. However, cutaneous lesions are occasionally diagnosed as the primary manifestation of leukemia. Leukemic skin infiltrations demonstrate considerable variation regarding a number of changes, distribution, and morphology. The highest incidence of LC is observed in chronic lymphocytic leukemia, monocytic and myelomonocytic acute myeloid leukemia, and T-cell lineage leukemia. Although the pathogenic mechanism of the invasion of leukemic cells into the skin is not well understood, chemokine receptors and adhesion molecules as well as the genetic characteristics of leukemia are thought to play a role. Leukemic skin lesions may be localized or disseminated and may occur alone or in combination on any site of the skin, most frequently in the trunk and extremities. The most common clinical presentations of leukemia cutis are papules, nodules, macules, plaques, and ulcers. In most patients, the complete or partial resolution of cutaneous infiltrations occurs simultaneously with hematologic remission. However, in patients with resistant disease or recurrent skin infiltration, local radiotherapy can be used. This review presents recent data on the pathogenesis, diagnosis, and treatment of leukemic skin involvement in different types of leukemia.

Leukaemia cutis as a specific skin involvement in chronic myelomonocytic leukaemia and review of the literature: Acknowledgments

The skin involvement of myeloid leukaemia is conventionally divided into specific malignant lesions and non-specific benign lesions, and these categories are also applicable in chronic myelomonocytic leukaemia (CMML). According to the 2016 World Health Organization (WHO) classification of tumours of haematopoietic and lymphoid tissues, CMML is defined as a myeloid neoplasm with characteristics of myelodysplastic syndrome (MDS) and myeloproliferative neoplasms (MPNs). As a specific cutaneous sign of extramedullary infiltration, leukaemia cutis (LC) is a rare occurrence in patients with CMML, and only approximately 89 cases have been reported in the literature thus far. The clinical features of LC are varied, and LC in CMML exhibits heterogeneous histopathologic features, with manifestations as cutaneous nodules or papules that are composed of blast cells showing either granulocytic or monocytic differentiation. Skin biopsy and further immunohistochemical examination are essential at the time of diagnosis to evaluate pathological type and determine the clinical course. Generally, once diagnosed as LC in CMML, this unusual skin lesion might be an indicator of transformation to acute myeloid leukaemia (AML) and is associated with a poor prognosis. The main treatment is allogeneic stem cell transplantation (ASCT). Therefore, early diagnosis and accurate identification have important therapeutic and prognostic significance in CMML patients with skin infiltration.

Leukemia cutis in a medical center in southern Taiwan: A retrospective study of 42 patients

BACKGROUND/PURPOSE

Leukemia cutis (LC), by definition, is the infiltration of neoplastic leukocytes in the skin. The overall incidence of LC is rare. We aimed to investigate the association between clinical characteristics, classifications and prognosis among different types of LC in Taiwan.

METHODS

We performed a retrospective analysis of forty-two patients with histopathology proven LC based on skin biopsies in a medical center in Southern Taiwan from 1997 to 2018. The study involved medical records of the patients, clinical manifestations, and outcomes according to different types of leukemia.

RESULTS

This series consisted of 27 males and 15 females, and the mean age was 55.7 years old. The most common cutaneous features were papules (38%) and nodules (29%), followed by plaques (16%) and ulcers (10%). The most commonly affected sites were the trunk (33%) and extremities (31.5%), although generalized distribution (14%) was not rare. The prognosis of LC was very poor, 76.2% of patients (32/42) died during the follow-up, and the median survival time was 7.2 months (95% CI, 4.53-9.87 months). No statistical significance was found (P = 0.068 for survival curves) among different types of LC.

CONCLUSION

This study was the first large-scale research in regarding to LC of Han Chinese. The commonest clinical presentations were papules and nodules, and the predilection sites were trunk and extremities. Besides, there was the high frequency of LC from AML and MDS in Taiwan. Clinicians should pay more attention to the leukemia patients with extramedullary manifestations due to poor survival outcomes.

Analysis of 59 cases of congenital leukemia reported between 2001 and 2016

Congenital leukemia (CL), defined as manifestations of leukemia within the first 4 weeks of life, is a rare condition with an estimated incidence of only 1 to 5 per million live births. Despite extensive research and the clinical application of new therapies, the prognosis of CL remains poor. Few large-scale studies have investigated the factors affecting the outcomes of infants with CL. Here, we conducted a retrospective study and analysis of CL cases published in the English language from 1 January 2001 to 1 May 2016. Our goal was to provide updated information about this rare disease and to investigate factors that may affect the outcomes of patients with CL.

Transient spontaneous remission in congenital MLL-AF10 rearranged acute myeloid leukemia presenting with cardiorespiratory failure and meconium ileus

Background

Neonatal leukemia is a rare disease with an estimated prevalence of about one to five in a million neonates. The majority being acute myeloid leukemia (AML), neonatal leukemia can present with a variety of symptoms including hyperleucocytosis, cytopenia, hepatosplenomegaly, and skin infiltrates. Chromosomal rearrangements including mixed lineage leukemia (MLL) translocations are common in neonatal AML.

Case presentation

A female neonate born at 34 weeks gestation presented with cardiorespiratory failure, hepatosplenomegaly, pancytopenia, and coagulopathy. She required intensive care treatment including mechanical ventilation, high-dose catecholamine therapy, and multiple transfusions. Small intestinal biopsy obtained during laparotomy for meconium ileus revealed an infiltrate by an undifferentiated monoblastic, MLL-rearranged leukemia. No other manifestations of leukemia could be detected. After spontaneous clinical remission, lasting 5 months without any specific treatment, the patient presented with leukemia cutis and full-blown monoblastic leukemia. MLL-AF10-rearranged AML could be re-diagnosed and successfully treated with chemotherapy and hematopoietic stem cell transplantation.

Conclusions

Our patient exhibited a unique manifestation of neonatal MLL-AF10 rearranged AML with cardiorespiratory failure and intestinal infiltration. It highlights the importance of leukemia in the differential diagnosis of neonatal distress, congenital hematological abnormalities, and skin lesions.

The Skin as an Early Expression of Malignancies in the Neonatal Age: A Review of the Literature and a Case Series

Skin lesions are a frequent finding in childhood, from infancy throughout adolescence. They can arise from many conditions, including infections and inflammation. Most neonatal rashes are benign and self-limiting and require no treatment. Other conditions may be an expression of malignancy or may be a marker for other abnormalities, such as neural tube defects. Therefore, skin lesions require an extensive evaluation and close follow-up to ensure the best possible outcome. This paper briefly reviews the main tumor types presenting with cutaneous involvement in neonates, followed by the description of some patients admitted to our Neonatal Intensive Care Unit with an early skin expression of malignancies.

Neonatal leukaemia cutis

Neonatal leukaemia cutis is a significant neoplasm that may represent a cutaneous manifestation of systemic leukaemia, usually of myeloblastic type. Rarely, it may be or appear to be limited to skin, in which case it is called neonatal aleukaemic leukaemia cutis. By definition, it presents within the first 4 weeks of life and often has a 'blueberry muffin baby' appearance of magenta coloured nodules affecting almost any area of the skin, usually sparing mucous membranes, palms and soles. This clinical pattern is more commonly associated with neonatal infections such rubella and toxoplasmosis, and may be evident with other neonatal neoplasms such as neuroblastoma. Due to the morbidity associated with chemotherapy and reported cases of spontaneous remission without systemic progression in those with neonatal aleukaemic leukaemia cutis without 11q23 translocation, the authors not treating the child with chemotherapy, but to simply monitor for fading of the violaceous nodules, and watch for possible signs of systemic leukaemia.

Congenital papulonodular eruption: presenting sign of congenital leukaemia cutis

Congenital leukaemia (CL) is a rare malignancy that accounts for < 1% of cases of childhood leukaemias. Leukaemia cutis (LC) refers to cutaneous infiltration with leukaemic cells, and is seen in 30-50% of CL cases. It may precede, follow or occur simultaneously with leukaemia. If left untreated, the prognosis is usually poor, but early diagnosis and treatment may result in a favourable prognosis. We report a case of congenital leukaemia cutis with a progressive, violaceous papulonodular eruption (a 'blueberry muffin' rash), which had been noted at birth, as a presenting sign of acute myeloid leukaemia (AML), which on investigation was classified as AML, FAB M2 type with a t(8; 21)(p11;q22) chromosomal defect. The patient had a favourable response to AML chemotherapy.

Congenital acute lymphoblastic leukemia: a two-case report and a review of the literature

Congenital leukemia is a rare disease with particular biological and clinical characteristics which differs from those of older children and adults. Here, we describe two cases of congenital acute lymphoblastic leukemia in two newborns with different clinical presentations (leukemia cutis vs. splenomegaly and respiratory distress) and fatal outcome. Both cases shared the expression of myeloid antigens (CD65) and cytogenetic disorders involving the MLL gene (location 11q23) which are associated to extremely poor prognosis.

Congenital leukemia cutis presenting as multiple violaceous lesions in a newborn

We present a case of congenital leukemia cutis that was the presenting sign of systemic acute myeloid leukemia. The initial diagnosis was benign hemangiomatosis because ultrasound of the liver was negative for visceral involvement. However, biopsy showed monocytic cells and led to a further workup which involved a bone marrow biopsy, giving the final diagnosis of acute myeloid leukemia with leukemia cutis. Even with a thorough knowledge of the differential diagnosis of such presenting lesions, a diagnostic biopsy is often needed for a final histologic diagnosis, to proceed with the proper course of treatment. We review congenital leukemia cutis and the differential diagnosis for violaceous lesions in the newborn that may be encountered by the pediatric plastic surgeon.

Congenital acute myeloid leukemia with t(8;16) and t(17;19) double translocation: case presentation and literature review

Congenital leukemia is uncommon and excluding transient myeloproliferation associated with Down syndrome, makes up approximately 1% of childhood leukemias. A newborn boy was born with multiple subcutaneous nodules and large purpuric papules. Skin biopsy revealed proliferation of atypical hematologic cells in the dermis. Bone marrow morphology was consistent with acute myeloid leukemia (M5) and cytogenetic studies revealed t(8;16) and t(17;19) double translocation. Although prognosis of congenital leukemia is known to be dismal, recent reports showed spontaneous remissions. With the fear of chemotherapy-related toxicity, to treat or not to treat may be a dilemma both to parents and pediatricians. We report our experience and review the literature.

A case of congenital leukemia cutis

Congenital leukemia is a rare disease that develops from birth to 6 weeks of life. Leukemia cutis involves cutaneous infiltration by leukemic cells and is an unusual manifestation of leukemia, and has been documented in 25~30% of patients with congenital leukemia. The authors report a case of congenital leukemia cutis. A newborn male presented with widespread firm dusky red papules and nodules on almost his entire body surface. Skin biopsy specimens confirmed the presence of leukemic infiltrations, and bone marrow cytology was consistent with acute myeloid leukemia of the FAB M5 type.

Spontaneous resolution of a single lesion of myeloid leukemia cutis in an infant: case report and discussion

Though infantile leukemia has a historically poor prognosis, there may be a subset of patients with cutaneous disease whose disease will resolve without therapy. The authors report a case of infantile leukemia cutis who presented with a single subcutaneous chloroma that spontaneously resolved over the course of several weeks and who remains without evidence of disease nearly two years later. After reviewing the literature of congenital leukemia cutis, the authors conclude that withholding chemotherapy in infants with cutaneous myeloid leukemia in the absence of known negative prognostic factors (MLL or BCR-ABL translocations) or progressive disease is clinically indicated.

[Leukaemia cutis during acute aleukaemic myeloid leukaemia in a two-month-old infant]

BACKGROUND

Congenital cutaneous leukaemia is rare.

PATIENTS AND METHODS

A two-month-old girl presented bluish cutaneous macules of the trunk, histological examination of which suggested acute myeloid leukaemia (LAM B 5). The blood picture was negative for circulating tumour cells and the outcome under chemotherapy was favourable at one year of follow-up.

DISCUSSION

The prognosis of congenital leukaemia is serious. Aleukaemic congenital leukaemia is seen occasionally but is rare. The existence of multiple cutaneous tumours in newborn infants raises the possibility of TORCH infection and of other malignant tumours such as nephroblastoma or neuroblastoma.

Leukemia cutis

Leukemia cutis (LC) is a nonspecific term used for cutaneous manifestations of any type of leukemia. LC has a wide range of cutaneous manifestations, which can make it difficult to clinically distinguish LC from other skin lesions. Patients with LC usually have concomitant systemic leukemia, but occasionally skin involvement precedes the involvement of the bone marrow or peripheral blood. Thus, a skin biopsy can be the first indication of the presence of leukemia in a subset of patients. The immunophenotyping of routinely processed skin biopsy specimens is very useful in establishing the diagnosis of LC. Although the molecular mechanisms explaining the pathogenesis of LC are not well defined, chemokine receptors and adhesion molecules may have an important role in skin tropism. We review the literature and recent advances pertaining to LC, with special emphasis on the immunohistochemical assessment and possible mechanisms involved in skin tropism by leukemic cells.
