LAB Assignment for Health Assessment Lab Assignment: Differential Diagnosis for Skin Conditions Properly identifying the cause and type of a patient’s skin condition involves a process of elimination known as differential diagnosis. Using this process, a health professional can take a given set of physical abnormalities, vital signs, health assessment findings, and patient descriptions of symptoms, and incrementally narrow them down until one diagnosis is determined as the most likely cause. In this Lab Assignment, you will examine several visual representations of various skin conditions, describe your observations, and use the techniques of differential diagnosis to determine the most likely condition.

To Prepare · Review the Skin Conditions document provided in this week’s Learning Resources, and select one condition to closely examine for this Lab Assignment. · Consider the abnormal physical characteristics you observe in the graphic you selected. How would you describe the characteristics using clinical terminologies? · Explore different conditions that could be the cause of the skin abnormalities in the graphics you selected. · Consider which of the conditions is most likely to be the correct diagnosis, and why. · Search the Walden library for one evidence-based practice, peer-reviewed article based on the skin condition you chose for this Lab Assignment. · Review the Comprehensive SOAP Exemplar found in this week’s Learning Resources to guide you as you prepare your SOAP note. · Download the SOAP Template found in this week’s Learning Resources, and use this template to complete this Lab Assignment.

The Lab Assignment · Choose one skin condition graphic (identify by number in your Chief Complaint) to document your assignment in the SOAP (Subjective, Objective, Assessment, and Plan) note format rather than the traditional narrative style. Refer to Chapter 2 of the Sullivan text and the Comprehensive SOAP Template in this week's Learning Resources for guidance. Remember that not all comprehensive SOAP data are included in every patient case. · Use clinical terminologies to explain the physical characteristics featured in the graphic. Formulate a differential diagnosis of three to five possible conditions for the skin graphic that you chose. Determine which is most likely to be the correct diagnosis and explain your reasoning using at least three different references, one reference from current evidence-based literature from your search and two different references from this week’s Learning Resources.

Introduction

Accurate diagnosis of skin conditions is crucial in providing effective treatment and management for patients. The process of differential diagnosis involves a systematic approach to distinguish among various potential causes based on clinical observations, patient history, visual examination, and supporting diagnostic data. In this paper, I will examine a selected skin condition graphic, describe its clinical features, propose differential diagnoses, and justify the most probable condition based on evidence and clinical reasoning.

Observation and Clinical Description

The selected skin graphic depicts a lesion characterized by erythema, scaling, and well-demarcated borders. The lesion appears raised, with a silvery-white scale overlaying the erythematous base. The texture is rough, and the distribution covers the extensor surfaces of the elbows and knees. Using clinical terminology, the lesion exhibits features consistent with plaques—raised, flat-topped, and silvery in appearance—suggestive of psoriasis vulgaris (Gordon & Eichenfield, 2020). The lesion’s well-demarcated borders and silvery scale are typical of chronic, inflammatory skin conditions.

Differential Diagnosis

Based on the visual presentation, several conditions could present with similar features:

  1. Psoriasis Vulgaris: Chronic autoimmune condition characterized by hyperproliferation of keratinocytes, leading to erythematous plaques with silvery scale, commonly on extensor surfaces.
  2. Seborrheic Dermatitis: Presents with erythematous patches with yellowish greasy scales, primarily affecting scalp and face, but can involve other areas.
  3. Lichen Planus: Flat-topped, violaceous papules with Wickham’s striae, often pruritic, affecting wrists and oral mucosa.
  4. Eczema (Atopic Dermatitis): Erythematous, itchy, and scaling patches, often with ill-defined borders and lichenification in chronic stages.

Considering the sharp border, silvery scale, and location, psoriasis vulgaris is the most likely diagnosis.

Justification of Most Likely Diagnosis

The most probable diagnosis is psoriasis vulgaris due to its classic presentation—erythematous plaques with silvery scales localized on extensor regions, characteristic skin pattern, and chronicity. The absence of greasy scales rules out seborrheic dermatitis, and the lack of violaceous coloration and Wickham’s striae suggests it is less likely to be lichen planus. Furthermore, the pattern differentiates it from eczema, which usually exhibits more diffuse and ill-defined borders, and is often associated with pruritus (Rachanioti et al., 2023).

Evidence-based literature underscores that psoriasis is diagnosed primarily through clinical appearance, supported by histopathology in uncertain cases (Nestle et al., 2009). A peer-reviewed article by Johnson et al. (2021) emphasizes the importance of recognizing the characteristic features, including the sharply defined plaques with silvery scale, in guiding diagnosis and management.

Conclusion

The process of differential diagnosis in dermatology relies heavily on visual assessment, clinical history, and appropriate use of medical terminology. In the selected graphic case, psoriasis vulgaris presents with hallmark features that distinguish it from other dermatoses. Recognizing these key characteristics allows clinicians to establish an accurate diagnosis promptly and tailor effective treatment strategies.
