Cervical Adenopathy Icd 10

Cervical lymphadenopathy refers to the swelling of lymph nodes located in the neck. Lymph nodes, situated all over the body, are part of the lymphatic system, which works to protect the body against microbes, maintain adequate fluid levels, absorb nutrients, and remove certain waste products. Lymphocytes, or white blood cells, are activated in the lymph nodes, after which they travel into the bloodstream to defend the body against microbes. When the lymph nodes accumulate excessive amounts of lymphocytes, they can increase in size and become swollen. 

Cervical lymphadenopathy can often be confused with cervical lymphadenitis. Although cervical lymphadenitis does usually present with cervical lymphadenopathy, cervical lymphadenitis refers to a direct infection of the cervical lymph nodes, often resulting from bacterial or viral infection. Cervical lymphadenitis can occur from Mycobacterium tuberculosis, resulting in tuberculous cervical lymphadenitis, or by other atypical mycobacteria, resulting in non-tuberculous cervical lymphadenitis. Additionally, cat scratch disease, which is caused by the bacterium Bartonella henselae, can result in cervical lymphadenitis. 

Cervical lymphadenopathy may be a non-specific clinical sign of an underlying disease, requiring further investigations depending on additional clinical features presented by the individual. Additional information that may be useful for a physician include the duration of the lymphadenopathy, the characteristics of the lymph nodes, and involvement of lymph nodes in other body areas.

Treatment for cervical lymphadenopathy will vary based on the underlying cause, and will typically resolve with appropriate treatment of the underlying condition. 

Cervical lymphadenopathy on its own is not a serious condition; however, it may indicate a more serious underlying condition. In many cases, it can be a sign of a mild, benign, self-limiting condition of acute onset. However, it can also be a sign of more serious chronic conditions, such as cancer or autoimmune diseases, and should be thoroughly evaluated in order to make a sound diagnosis.

Mrs Tan took her daughter Emma, a well-thrived three-year-old girl, to the family clinic for two days of fever, sore throat and rhinorrhoea. Apart from slight decreased appetite, Mrs Tan reported that Emma’s activity level and behaviour were not affected. During the examination, Emma was interactive, her nose was congested with clear rhinorrhoea, and there was pharyngeal injection without exudates. You discovered bilateral non-tender, mobile cervical lymph nodes that were up to 1.5 cm in size. Mrs Tan was uncertain if they were present prior to her current illness. There was no organomegaly or other lymphadenopathy. You treated Emma for viral respiratory tract illness and made plans to review her in two weeks for her cervical lymphadenopathy

Lymphadenopathy is defined as the presence of one or more lymph nodes of more than 1 cm in diameter, with or without an abnormality in character.(1) In children, it represents the majority of causes of neck masses, which are abnormal palpable lumps or swellings.

Cervical lymphadenopathy in the paediatric population is common in general medical practice and presents either as a primary complaint of neck mass or as an incidental finding during clinical examination. Park reported that 90% of all children aged 4–8 years have palpable lymphadenopathy.(2) In a systematic review of paediatric cervical lymphadenopathy involving 2, 687 patients, two thirds of the cases were due to non-specific benign aetiology with no definitive diagnosis, and 4.7% were secondary to malignancy.(3)

When first reviewing a child with cervical lymphadenopathy, the primary care physician is faced with a conundrum – manage at primary care or refer for specialist review? We propose that the physician’s familiarity with the differential diagnoses of lymphadenopathy and neck masses increases the success rate of managing this in primary care. An evidence-based evaluation framework may reduce unnecessary diagnostic tests and therapies, as well as enable physicians to counsel their patients and caregivers appropriately.

In the initial approach, it is important to first consider the broad differential diagnosis of cervical lymphadenopathy, including other causes of neck masses that may mimic it closely (

Table I).(4) Neck masses in children can be classified into congenital or acquired causes. Congenital lesions are usually painless and may be identified at or shortly after birth. They may also present with chronic drainage or recurrent episodes of swelling, which may only be obvious in later life or after a secondary infection. The location of the mass is often useful in narrowing down the diagnosis. Notably, midline masses are often not due to lymphadenopathy. The sternocleidomastoid muscle is used as an important surface landmark to distinguish between the anterior and posterior triangles of the neck.

A thorough history and physical examination are fundamental steps in the evaluation of a child with the complaint of a neck mass.

A complete physical examination always includes a general inspection of the child’s growth parameters (i.e. growth charts) and general health status. The presence of pallor or jaundice should be determined. In addition to the location of the neck mass, it is important to examine the following:

In a child with cervical lymphadenopathy, the duration of lymphadenopathy is a key consideration in determining its possible aetiology, which can be categorised into four main groups: infectious, immunologic, malignancy and miscellaneous causes. The causes can then be classified according to the origin and time course of symptoms, as presented in

The most common scenario of acute cervical lymphadenopathy is enlargement of bilateral lymph nodes in the correct nodal drainage chain during an acute infection. This represents a self-limiting, transient response of lymphatic tissue hyperplasia to a local infective process that improves with resolution of the viral illness. In the absence of red flags, it can be managed according to

Ebstein-Barr virus (EBV) and cytomegalovirus (CMV) infections may be more common in older children of school-going age and adolescents. Children with EBV infection often present with a clinical picture of infectious mononucleosis, characterised by generalised lymphadenopathy, sore throat, fatigue and fever. This may be accompanied by exudative tonsillitis and hepatosplenomegaly.

Children can also present with acute unilateral cervical lymphadenitis, caused by bacterial infection. Lymphadenitis is defined as lymphadenopathies caused by an inflammatory process, resulting in enlarged, tender lymph nodes with or without overlying erythema.(6) The most common causative pathogens are

).(5) The primary source of infection may or may not be found. Acute unilateral cervical lymphadenitis most often affects children aged 1–4 years. Some may progress to have abscess formation. Less commonly, it may be caused by anaerobic bacteria associated with dental infections and abscesses.

An important distinguishing feature between viral and bacterial lymphadenitis is whether there is self-resolution. Primary bacterial lymphadenitis or a viral lymphadenitis with secondary bacterial infection should be considered if the patient does not improve after 4–7 days.

KD is the most common childhood acute vasculitic disease of unclear aetiology and is associated with the development of coronary artery complications. It mainly affects children under five years of age. The diagnosis is clinical, based on the presence of fever lasting five days or more, and a constellation of symptoms, which may not all be present. These include polymorphous exanthem, bilateral non-suppurative conjunctivitis, changes in lips and oral mucosa, changes in extremities, and usually unilateral cervical lymphadenopathy measuring more than 1.5 cm. KD should be considered in a child with persistent fever and cervical lymphadenitis despite the use of antibiotics.

Most reports in the literature describe KD as an uncommon cause of cervical lymphadenopathy, with the highest incidence in Asian countries, in particular Japan, South Korea and Taiwan.(7) However, in the wake of the current coronavirus 2019 (COVID-19) pandemic, there has been increasing interest in KD in European countries with large COVID-19 outbreaks. These countries have reported cases of a paediatric multi-system inflammatory syndrome, where critically ill children present with features of shock and Kawasaki-like disease, which may be temporally associated with COVID-19 infection.(8) Although Singapore has not yet seen such cases among the paediatric population, the Ministry of Health has issued an advisory for medical practitioners to be aware of this condition. This further highlights the importance of early recognition of KD at a primary care level, to facilitate early specialist referral.

Kikuchi-Fujimoto disease, also known as histiocytic necrotising lymphadenitis, is a lesser known clinical entity but is not as uncommon as previously perceived. It usually presents in older children and adolescents, most commonly aged 7–12 years, with unexplained fever and cervical lymphadenopathy. Accompanying symptoms include weight loss, night sweats, chills, rash and arthralgia. Although generally understood to be a self-limiting, benign condition of unknown aetiology, it can lead to significant complications including aseptic meningitis, with reports of progression to systemic lupus erythematosus.(9) A biopsy of the lymph node is required for histopathological diagnosis.
