ASSESSMENT

Differential Diagnosis 1: Cellulitis.

Cellulitis, commonly referred to as streptococci, is a skin infection that affects

subcutaneous skin layers and causes severe pain in the affected areas (Patel et al., 2018). The

skin condition is caused by an unknown streptococcus. The condition occurs when pathogens

enter the subcutaneous layers through broken skin. The condition is also difficult to diagnose and

distinguish from other skin conditions, which manifest in very similar ways. The disease

manifests in a subcutaneous region with an inferior boundary, mostly in the lower extremities.

However, the disease can also occur in the upper extremities if a patient is administered

an intravenous drug. The disease is accompanied by inflammatory signs, consisting of fever,

swelling, tenderness, and pain in the infected area. From graphic 4, the patient has red and

slightly swollen skin on the lower extremity, with visible sores. The accident that led to hitting

the leg on a surface may have caused the streptococcus to penetrate the skin and cause Cellulitis.

Differential Diagnosis 2: Erysipelas

Erysipelas is a skin infection of the dermis, which mainly manifests in the lower limbs or

face. The disease's symptoms include skin tenderness, a well-delineated and raised erythema,

fever, and malaise. The disease is caused by Streptococcus Pyogenes, a bacterium that is also

referred to as hemolytic streptococci (Brindle et al., 2020). The bacteria enter the skin through a

scratch of the skin or through an insect bite. The disease has very similar signs and symptoms to

9

Cellulitis, but it is usually more demarcated and raised. Signs of the symptoms include a red

plaque, a raised edge, swollenness, tenderness, and warmth of the skin on the affected area.

Differential diagnosis 3: Necrotizing

The disease is a severe skin infection affecting the subcutaneous later and skin facia and

is prevalent in the lower skin areas (Puntis, 2018). The disease spreads fast and often calls for

emergency surgery. Its symptoms include fever, swelling, tenderness, and pain in the infected

area, which are very close to those of Cellulitis. The symptoms keep on changing with time,

unlike Cellulitis, whose symptoms are very specific. In the later stages, the disease manifests in

the form of gas gangrene and necrosis. From graphic number four, the patient has tenderness of

the skin, red ores, and swelling, but lacks any signs of gas gangrenes, thus disqualifying the

Necrotizing diagnosis.

Differential Diagnosis 4: Erythema nodosum

Erythema nodosum is a skin infection commonly located at the lower extremities and

manifests in the form of erythematous and nodular eruption (Gilchrist & Patterson, 2010). The

disease is considered a reaction caused by hypersensitivity to immune depositions by vessels

located in the panniculus adiposis. It is also comorbid with other systemic diseases and certain

therapeutic interventions.

Differential diagnosis 5: Contact Dermatitis

The disease is an itchy rash caused by contact with a substance that causes an allergic

reaction to the skin. Such substances include plants, cosmetics, jewelry, and fragrances. Signs

and symptoms include swelling, warmth, or tenderness of the skin on the affected region, an

itchy rash, blisters, and leathery patches (Marty & Cheng, 2005).

10

Primary Diagnoses: While many skin diseases manifest with similar symptoms, there are

distinguishing features that set apart a specific disease. Considering that the person hit his leg

on a blunt object which did not cause broken skin, but the disease emerged after the accident,

it is most likely that bacteria entered the skin during the impact, thus implying a high

likelihood of Cellulitis. Also, the disease affected the subcutaneous tissue, whic
