60 year old diabetic female presented with burning sensation to spicy food. Intraoral examination revealed multiple periodontal abscess and keratotic area in a lace pattern with occasional erosive areas inside the lace pattern. Provisional diagnosis for this lady will be
**Core Concept**
The patient's presentation suggests a chronic condition affecting the oral mucosa, characterized by keratotic lesions, periodontal abscesses, and sensitivity to spicy food. This condition is often associated with an underlying systemic disease, particularly diabetes mellitus.
**Why the Correct Answer is Right**
The patient's symptoms and clinical findings are indicative of **oral lichen planus (OLP)**. OLP is a mucocutaneous condition characterized by the presence of white, lacy (reticular) lesions on the mucous membranes, which can be accompanied by erosive areas. The condition is often linked to autoimmune disorders, and its presence in a patient with diabetes mellitus suggests a possible association with the patient's systemic disease.
The pathogenesis of OLP is thought to involve a complex interplay between immune system dysregulation, genetic predisposition, and environmental factors. The condition is characterized by the presence of activated T lymphocytes in the affected mucosa, which leads to the release of pro-inflammatory cytokines and the subsequent development of clinical lesions.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **oral thrush** typically presents with white, cheesy patches on the mucous membranes, which are not consistent with the patient's clinical findings.
**Option B:** This option is incorrect because **oral cancer** typically presents with a sore or ulcerative lesion that does not resolve, whereas the patient's lesions are characterized by a lace-like pattern and sensitivity to spicy food.
**Option C:** This option is incorrect because **oral candidiasis** typically presents with a white, cheesy plaque on the mucous membranes, which is not consistent with the patient's clinical findings.
**Clinical Pearl / High-Yield Fact**
The presence of oral lichen planus in a patient with diabetes mellitus highlights the importance of considering the patient's systemic disease when evaluating oral lesions. A thorough medical history and examination are essential in making an accurate diagnosis and developing an effective treatment plan.
**Correct Answer:** C. Oral lichen planus.
