A patient presented with skin pigmentation, hyperglycemia and his serum ferrith level is 900 microgram/l, possible diagnosis-
**Core Concept**
The patient's presentation suggests a diagnosis related to iron overload, skin pigmentation, and glucose metabolism abnormalities. This condition is associated with increased iron storage, which can lead to oxidative stress and damage to various organs, including the pancreas.
**Why the Correct Answer is Right**
The patient's symptoms are consistent with **Hemochromatosis**, a genetic disorder characterized by excessive iron absorption and accumulation. The elevated serum ferritin level supports this diagnosis. The skin pigmentation is likely due to the deposition of iron in the skin, leading to a bronze or slate-gray color. The hyperglycemia is a result of the iron overload damaging the pancreatic beta cells, leading to impaired insulin production.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because **Wilson's disease** is a different genetic disorder that affects copper metabolism, not iron.
**Option B:** This option is incorrect because **Thalassemia** is a blood disorder characterized by reduced production of hemoglobin, which can lead to iron deficiency anemia, not iron overload.
**Option C:** This option is incorrect because **Porphyria** is a group of disorders related to heme synthesis, which can cause skin pigmentation and other symptoms, but it is not associated with iron overload.
**Clinical Pearl / High-Yield Fact**
Hemochromatosis is often referred to as the "bronze diabetes" due to the characteristic skin pigmentation and glucose metabolism abnormalities associated with the condition.
**Correct Answer:** C.
