Cutaneous Presentations Of Systemic Diseases

Cutaneous Presentation of Systemic Diseases

SBE (sub-acute bacterial endocarditis) Emboli trapped at the capillary beds show as micro- hemorrhages or infarcts.

Nail bed pathology Differentiate from Hutchinson’s Sign for melanoma Superficial Spreading: most Clubbing of nails can be seen in common and seen on back and trunk. pachydermoperiostosis syndrome Can become nodular (seen in lung cancer— bronchogenic or alveolar cell Nodular: vertical growth phase carcinoma Bazex’s syndrome (yellow nails Acrolentigenous: seen on digits with violaceous color of skin) seen and subungual areas, more common in lung cancer blacks Terry’s Nails (ground glass Lentigo Maligna: least common, appearance to nails) can be seen usually on face or other actinic in CHF exposure areas

Acute Leukemias (non-lymphoblastic) Uncontrolled proliferation of hematopoietic cells with malignant cells filling marrow and other tissue and with the reduced production of erythrocytes, granulocytes and megakaryocytes, anemia, infection and hemorrhage results. 80% incidence of ALL (acute lymphoblastic leukemia) in children 80% incidence of ANLL (acute non-lymphocytic leukemia) in adults Classification is via predominant neoplastic cell line (lymphoblastic or non-lymphoblastic [myeloblastic/monocytic]) Sub-classified by the FAB (French/American/British) group

Acute Leukemias (non-lymphoblastic) Etiologies include chromosomal damage from radiation, chemicals (e.g., benzene and alkylating agents used in therapy), congenital diseases (e.g., Down’s syndrome), and chronic bone marrow diseases (e.g., myeloid metaplasia), congenital predisposition, and congenital immunodeficiency syndromes (e.g., ataxia-telangiectasia). In acute leukemia, the uncontrolled proliferation of hematopoietic cells in the bone marrow and peripheral blood eventually replace the marrow and invade other tissues and organs. The manifestation of the disease results in diminished production of erythrocytes, granulocytes and megakaryocytes with resulting anemia, infection and hemorrhage. As the degree of marrow and other organ involvement progresses, symptoms of fatigue, ecchymosis, buccal lesions and infection increase. Peri-rectal infections are often seen in ANLL with skin and gum infiltrates seen an acute monocytic leukemia. Rheumatic symptoms occur commonly with ALL, as well as lymphadenopathy and hepatosplenomegaly. Patients with ANLL can have unusual masses in the soft tissue and nodal sites, as a precursor of overt marrow and peripheral blood invasion and may be mistaken for lymphoma. These are called myeloblastomas.

Acute Leukemias (non-lymphoblastic) Degree of organ or marrow involvement will dictate the types of lesions Skin and gum infiltrates are commonly seen in AML (Candida albicans) Leukemic infiltration of the gums in AMOL Peri-rectal infections are frequent in ANLL Joint swelling and bone pain with rheumatic symptoms is seen in ALL

Acute Leukemias (non-lymphoblastic) • Sweet’s syndrome: acute febrile neutrophilic dermatosis. Seen in AML or AMOL (acute monocytic leukemia). Seen here in ANLL (acute non-lymphocytic leukemia [1]) • Usually drug-induced or following a viral 3 illness in the young • 10% incidence of underlying cancer, most commonly myelocytic leukemia (1-3) 1 • Nonmyelocytic leukemia and lymphoma have been reported (4) • Other cutaneous presentations: 4 2 – Arm in AML (2) – Leg in AML (3) – Scalp in ANLL (4)

Acute Leukemias (non-lymphoblastic) • Bone involvement: acute leukemic infiltration with necrosis marked by yellow opacification of the marrow with surrounding hyperemic tissue.

Acute Leukemias (non-lymphoblastic) AML-induced Pseudomonas pyocyanea • infection at the foot and hand • Streptococcal cellulitis at the neck and face all induced by the neutropenia from the prior chemotherapy for AML

Acute Leukemia (lymphoblastic) • B-cell lymphoma (Burkitt’s) • T-cell (Sézary syndrome)

Graft vs. Host Disease • Acute leukemia therapy (allogenic bone marrow transplant) can result in morbidity/mortality. This is seen as a range from papulosquamous eruptions or desquamation of the skin, with the palmar and plantar areas most commonly involved, as in this patient with AML

Chronic Leukemias 3 • CLL (chronic lymphocytic leukemia) presenting as lymphadenopathy (1) • CLL converting to DLCL (diffuse large cell lymphoma) with trunk lesion which shows B-immunoblastic type diffuse large cell lymphoma or Richter’s syndrome (2) 4 1 • CLL-induced herpes zoster lesions (3) with buccal infection with Candida albicans (4) • CLL-induced pharyngeal tonsil enlargement (5) 2 5

Chronic Leukemias • CML can present with hyperviscosity syndrome and hepatosplenomegaly. Note the splenic infarct (white spot at the surface of the spleen

Lichen Planus • Inflammatory, muccocutaneous condition with common 1 morphology • Long-term oral mucosal lesions (1) have an increased risk of developing squamous cell carcinoma. Same with genital lesions. • Causes include drug eruptions and HCV infection, although most cases are idiopathic • Treatment includes oral and topical steroids, Soriatane, 2 PUVA and possibly Dapsone and Plaquenil • Usual presentation is a violaceous polygonal flat-top papule (2) and plaque with white scales (Wickham’s striae) • Variations include: – a hypertrophic version (3) 5 – Vesiculobullous (4) and actinic type (5) variants 4 – Nail and subungual presentation 3

Pemphigus Vulgaris • Autoimmune disease with bullous lesions which rupture leaving a denuded patch called “Nikolsky’s sign” • Can be associated with thymoma and myasthenia gravis • Paraneoplastic pemphigus is associated with cancer, most commonly non-Hodgkin’s lymphoma with 90% mortality due to sepsis or respiratory failure

Erythema Gyratum Repens • Wood grain pattern in the skin • 90% associated with internal cancer • Most commonly lung • Less commonly esophagus and breast

Breast Cancer • Cutaneous presentation seen in 1% of patient population. • Can be direct extension of the tumor or of local or distant metastasis • Direct extension most common with breast cancer and oral cancer

Ovarian Cancer • Malignant, cutaneous lesions indicative of systemic cancer are typically nodular with a firm consistency and are red, plum- colored or hyperpigmented • Ulceration of the lesions suggest an underlying cancer

Other Signs • Flushing, usually evident in the face and upper chest, most commonly accompanies carcinoid tumors of the intestine • Palmar erythema, usually associated with advanced liver failure, may also accompany primary or metastatic malignant liver disease • Direct extension of breast cancer to the skin may be accompanied by telangiectasia • Purpuric lesions may be a manifestation of disseminated intravascular coagulation induced by cancer.
